The Greatest Engineering Feat of the Century

Mars Opportunity Rover 10 Years Old

The Opportunity Rover on Mars is one of the greatest engineering success stories of the 21st century. Originally designed for a 3 month mission and still going 10 years later, it’s performed 40x longer than planned!

It’s saddening that a feat of engineering that in my mind equals that of say Brunel’s Clifton Gorge bridge, is not publicly recognised. Have you ever seen a show detailing it’s design or build? Do you know the names of anyone in the team that built it? The 10,000 word wikipedia page doesn’t even name the team involved in its design or construction, let alone any individual.

Actually that’s not strictly true, in the “Honors” section it says:

> “Honoring Opportunity’s great contribution to the exploration of Mars, the asteroid 39382 has been named Opportunity.”

And it then goes on to name 3 individuals: Ingrid van Houten-Groeneveld, Cornelis Johannes van Houten and Tom Gehrels, who found the asteroid. So yes the article does name some people, but they found a rock in space, one assumes the 39,382nd rock to be found in space!

But it doesn’t name a single engineer responsible for actually building a robot that flew to another planet and has spent 9 years and 3 months longer than planned, and certainly longer than anyone could have dreamed of, exploring it.

I know that engineers are not considered cool etc, but when something really remarkable happens, it’s a shame more effort is not made to recognise the achievement.

How to Buy a House in 6 Weeks

House Sold Sign

We’ve finally moved house, to just outside sunny(?) Warrington, and the piles of packed boxes in every room are slowly diminishing.

Moving house is always a stressful affair, but it was made somewhat easier by only taking 6 weeks from accepted offer, to walking in the front door with keys in hand, our fastest move to date. I thought it would interesting then to detail the timeline of what happened when, then at the end I’ll share my tips for moving house quickly, starting on the 3rd April:

  • 03/04 – Offer submitted to estate agents
  • 04/04 – Offer accepted via estate agents
  • 05/04 – Appointed solicitors
  • 09/04 – Mortgage approved in principal after receiving proof of income
  • 09/04 – Paid for Valuation
  • 09/04 – Arranged survey
  • 09/04 – Instructed solicitors to start searches – they’re waiting for the contract
  • 09/04 – Received vendor’s solicitor’s details
  • 10/04 – Returned our ID to the solicitor
  • 11/04 – Vendor returned ID and property details form
  • 12/04 – Received memorandum of sale
  • 12/04 – Valuation carried out
  • 12/04 – Survey carried out
  • 15/04 – Mortgage company approved mortgage based on valuation
  • 15/04 – Contract received by email from vendor’s solicitors
  • 16/04 – Searches started
  • 17/04 – Standard Valuation received by post
  • 17/04 – Formal mortgage offer received by post
  • 18/04 – Written survey received by post
  • 20/04 – Posted mortgage offer back
  • Various queries raised with vendor’s solicitors and answers flowing back
  • 30/04 – Mortgage company confirmed receipt of signed offer and waiting for completion date – needs 3 days notice to supply funds
  • 30/04 – Called to arrange quotes for removal
  • 03/05 – 1 of 3 removal quotes in
  • 07/05 – Still queries with solicitor outstanding, e.g. room details, road adoption certificates, retrospective approval for the new chimney etc
  • 08/05 – All removal quotes in.  All within 15% of each other.
  • 08/05 – Started moving deposit money to the solicitors (the bank needs original posted letter authorising a CHAPS payment so was 3 x BACS over 3 days)
  • 09/05 – Visit solicitors to sign the contracts
  • 09/05 – Called insurance company to arrange cover before exchange
  • 10/05 – Exchanged contracts for a completion date of 16/05
  • 10/05 – Called removal company to arrange removal, had to go to our 3rd choice company to get the date we wanted
  • 10/05 – Called telecoms provider to arrange phone line and broadband
  • 11/05 – Called bank to let them know to expect the solicitor to request funds and check funds delivery time
  • 13/05 – Called solicitor to ensure he was requesting funds today
  • 14/05 – Called bank to check they’d received the solicitor’s funds request and check the amount requested was right
  • 15/05 – Called solicitor to check funds had been received from the bank, they hadn’t!
  • 16/05 – Removal packers arrived to pack the house
  • 16/05 – @ 9:30am Called solicitor again, funds had arrived 5pm on the 15th and they were sending it on that morning
  • 16/05 – @ 11am – Completed!  Went to house to pick up the keys
  • 17/05 – Moved in, hurrah.

There you have it, 6 weeks from accepted offer to completion.  We’ve moved house a modest 6 times now and the first move took 3.5 months, so getting it down to 6 weeks I think I’ve learned a few things along the way.  Here are my 2 key tips for moving house quickly:

  1. Exchange mobile phone number (and land line preferably) with the seller and use it often.  All solicitors and estate agents involved are working for you two, but ultimately it’s a deal that’s being done between you and the seller, so communicate.  Often solicitors blame each other for issues or create delays in their formal communications, issues which can easily be resolved just by picking up the phone and calling the other party.  I called the seller probably 15 times over those 6 weeks, and he called me about 10, i.e. we spoke directly about 4 times a week.  Note also that I didn’t speak to the estate agent once we’d had the offer accepted, there’s usually little point.
  2. Don’t assume your solicitor and bank are infallible and will do what they say, when they say it will be done.  Keep on top of what’s happening and when; check everything and chase when you need to.  Great questions to ask you solicitor are:
    1. “What happen’s next?”
    2. “When will that get done?”
    3. “What are we waiting for right now?”

I hope your next move goes as quickly.

Do Power Lines Cause Cancer in Kids, e.g. Leukaemia?

Do Power Lines Cause Childhood Leukaemia

We’re moving house, and whilst writing it down like this sounds crazy, the estate we’ve picked is a few miles from a power station and has a set of main power lines and a few pylons running through it. (There are lots of plus points too, honest!)

Now everyone’s seen the “shock” headlines that power lines cause cancer right? I did someone tell me that? Or maybe I just thought they might? Anyway, I figured it was about the right time to properly investigate this and see whether it was true.

As a Chartered Electrical Engineer my first port of call was my governing body: the Institute of Engineers and Technicians (used to be the IEE) who have a working group to look at this exact issue (and that of mobile phones, tv and radio transmitters etc): the Biological Effects Policy Advisory Group. Here’s their latest policy statement, here is a fact file they’ve published on power lines and mobile phones, and here is a much more detailed fact sheet that looks at the whole issue: The Possible Harmful Biological Effects of Low-Level Electromagnetic Fields (EMF).

In summary the IET has been looking at this issue for 20 years and has been continually frustrated it seems in the fact that every time there’s a study that appears to show a link, it’s not able to be reproduced. I quote:

“… attempts have been made to replicate key studies, which have often been selected because of their apparently sound methodology, robustness and potential significance of findings… These attempts have been unable to confirm any of the original reports… the identification of even a single robust effect which could be used as a starting point to determine such factors as dose-response curves… has yet to be achieved.”

The issue is then that there are some studies that show links between power lines (what I’m interested in) and cancer rates, but that they are typically unreproducible, and as any scientist will tell you: if you can’t reproduce your findings, you haven’t found anything!

Actually I should be more clear, the studies that I’ve looked at don’t show a link between power lines and cancer, but specifically leukaemia, and then specifically only childhood leukaemia. That sounds bad right? Will maybe not as bad as you might think. Let’s look at one.

This study is published here in the British Medical Journal and is called: Childhood cancer in relation to distance from high voltage power lines in England and Wales: a case-control study. This is an epidemiological study which means they look at statistics and try to draw conclusions without any understanding of any science or mechanism behind it. You have to be very careful with epidemiological studies, as you constantly have to remind yourself that correlation and causation is not the same thing, and correlation does not mean causation. If you’re not convinced of that, ask me about pirates and their relationship with global warming some time. 😉

Anyway, back to the study. This UK study found that there was a 69% increase in leukaemia risk in kids who were born within 200m of power lines, and a 23% increase risk for those born between 200m and 600m. Those rates are relative to those that were born >600m away. What it didn’t find was any link with adult leukaemia rates. Nor did it find any increase in risk of other forms of cancer, including central nervous system (CNS) and brain tumours. If you’re so inclined, here’s some raw data that shows the distance of address at birth from nearest National Grid line for cases and controls in each diagnostic group, and estimated relative risk (RR):

Leukaemia CNS/brain tumours Other diagnoses
Distance /m  Cases  Controls  RR  Cases  Controls  RR  Cases  Controls  RR
0-49 5 3 1.67 3 7 0.44 7 6 1.17
50-99 19 11 1.79 4 6 0.69 15 16 0.91
100-199 40 25 1.64 26 32 0.82 37 45 0.81
200-299 44 39 1.16 38 28 1.35 66 76 0.87
300-399 61 54 1.15 35 30 1.19 79 65 1.21
400-499 78 65 1.23 40 42 0.96 80 97 0.82
500-599 75 56 1.36 54 41 1.33 86 85 1.01
≥600 (ref group) 9378 9447 1.00 6405 6419 1.00 12 406 12 386 1.00
Total 9700 9700 6605 6605 12 776 12 776

 

The problem with statistics is you can draw all sorts of interesting interpretations from results. For example you could say that living within 200m of a power line actually decreased your chance of getting a brain tumour! But you’d never see that in a newspaper headline of course.

Either way, this doesn’t look great. A 69% increased risk of getting leukaemia if born within 200m of a power line. So adults are ok, and other forms of cancer have been discounted, but the problem with this headline grabbing figure is that it’s a relative percentage. Relative to what?

lightningGolf

We all take relative risks every day. In the USA for example, 400 people out of 310M population get struck by lightning every year (1.29 per million). But not all 310M are likely to stand outside in a thunderstorm, unlike golfers. Now if we assume 1/4 were playing golf (I can’t find the exact stats) and there are 29M golfers in the USA so you could say (and you could cut the statistics many ways to get different figures, and I realise this is too simplistic but this is just an example to prove a point) that playing golf increases your risk of getting struck by lightning by 267%. But that doesn’t stop people playing golf, because getting hit by lightning is rare.

Just like you’re far more likely to crash and die if you ride a motorbike, but that doesn’t stop people doing it. Coming back to childhood leukaemia then, what does that 69% increased risk mean? Well there 2 figures that are really relevant:

  • There are about 400 cases of childhood leukaemia each year in the UK (ironically the same number of people struck by lightning in the USA!)
  • The number of incidents of childhood leukaemia that can be attributed to living near a power line is if five.

5!  I was astounded when I saw that number.  All this research and worry and the risks we’re talking about is 5, out of 400 cases.  So power lines (assuming this study is accurate) cause just over a 1% increase in leukaemia rates in children.

Taking that further, the overall survival rate for childhood leukaemia is now 80%, which means that whilst very very sad, only 1 child dies each year from this.  Assuming as I say, we believe this study.  I say that because even Cancer Research UK say that there’s no proven correlation with power lines.

I will conclude then by saying that I have no concerns about living near power lines, what flimsy and inconsistent evidence there is for a link with childhood leukaemia represents such a small risk, it’s not worth bothering about.  One child dies every 3 days on the UK’s roads, a death rate  that is over 100x higher than that due to the possible and unproven increase in leukaemia deaths, but we don’t stop our kids going outside.  I’ll leave you with the conclusion from the IET working group:

“Given the uncertainties about whether there are health effects or not, it is understandable that people may wish to reduce their personal exposure “just in case”. The Institution agrees with this approach, although this should only be as a stopgap until research delivers firmer answers one way or the other. But in view of the weakness of the scientific evidence for harmful effects, the Institution considers it would not be justifiable to take any measures that had a significant impact on lifestyle, or that were costly, or that affected the undoubted and major benefits to society of a reliable electricity supply and of widespread mobile communications.”

Why I Won’t Shop in PC World

Why I Won’t Shop in PC World post image

It’s been a while since I used this blog for what the internet invented blogs for: having a rant about things that pee you off! And as I woke up this morning thinking about this, I figured a bit of rant-therapy was in order.

I went into PC World in Stockport on Sunday to buy some DVD-R disks so that I could take a backup of my work’s Laptop. I don’t normally shop in PC World for the very reason that pee’d me off on Sunday, but Staples had shut and PC World was open, and I couldn’t think of anywhere else to buy DVD-R’s at 4:30pm on a Sunday.

It’s changed a lot since I was last in there, it’s become what Dixon’s used to be: and general peddler of all things electrical. Which is ironic as Dixon’s has disappeared from our high streets. Though not a lot realise that Dixon’s, PC World and Curry’s for that matter, are all owned by the same company.

Anyway, I eventually found the DVD-Rs and after drooling at the 60″ TVs for a bit, went to pay. As these were for business use, I asked for a VAT receipt. This is where it got messy, as the shop assistant then asked me for my name, physical address, email address and phone number. Which I refused to give.

Even after getting her supervisor, they refused to budge and wouldn’t give me a VAT receipt without be giving them my personal details. At one point the supervisor even said to me: “Well then you don’t need a VAT receipt!” To be fair, she did apologise later. The issues here are this:

– As a VAT registered company, PC World are obliged to give a VAT receipt if asked, that shows the tax component of the transaction.
– For retail sales under £250, a VAT invoice/receipt does NOT need the customer’s details.
– The Data Protection Act protects personal data from being collected, where it’s not necessary to collect it.

Knowing the law is on my side, and as I get enough junk mail, junk email, junk automated phone calls, I refuse to give out my personal details, just because someone asks for them. Realising that my Sunday afternoon didn’t need to be completely ruined by a blood pressure elevating episode in PC World, in the end just chose to walk away.

But it will be many more years before I step foot inside another PC World.

Blimey, it’s February 2013 already!

I’ve not been very good at updating my blog recently, life just seems to be getting in the way.

The reasons are that work has been very busy, which is good and bad at the same time. We’re also looking at moving house, so there’s been a lot more DIY in my life recently.

On the exercise front, I’ve managed to pickup another injury, this time a Direct Inguinal Hernia for which I’m awaiting surgery. It looks like a reoccurance of a childhood injury, but the main irony is that despite all the heavy lifting I’ve done in the last 5 years, I think I got it doing a Yoga stretching: specifically the Upward Dog!

And on a technical note, I managed to break my Dell Inspiron laptop last night. The bios update process failed and has left the laptop in a completely unbootable state. It won’t boot from DVD, USB stick or from the network. Dell premium telephone support can’t fix it. Nor can the local computer repair shop I’ve just heard from. Let’s hope Dell’s “Next Business Day Onsite Support” really is next business day…

Blog Issues

I’m having a few issues with this blog at the moment as a recent update has introduced some incompatibility and one of my plugins has broken. I’ve temporarily had to move to a different theme from normal which is why this site might look a bit different.

I’m going to be doing some fiddling over the next few days to see if I can sort this out, so the site may go in and out of maintenance mode and/or look screwy sometimes. I’ll try to keep disruption to a minimum.

Thanks for your patience and I hope you have a very Merry Christmas.

A Christmas CrossFit Poem

A Christmas CrossFit Poem post image

I was sent the following poem by a new FaceBook “friend” Jhaei Martin from the States. We originally got chatting about Obsessive CrossFit Disorder! She’s obviously got a hidden literary talent and has kindly allowed me to reproduce her poem here for all our enjoyment:

‘Twas the night before Christmas, when all through the box
Crossfitters were sweating in compression socks
The jumpropes were hung by the red bars with care,
In hopes that their coach soon would be there;
The newbies were hoping their muscles will shred
While the lists of WODs danced in Marisa’s head
And warm up on the white board should be done in a snap
but add-ons were listed so no time for a nap-
Then out on the lot there arose such a clatter,
Josue sprang from his corner to see what’s the matter.
Away to the window he flew like a flash,
Tore open the shutters, and threw up the sash.
The sun through the glass now all aglow
Gave the blinding reflection to bars below;
When, what to his wondering eyes should appear,
But a miniature sleigh, full of Reebok gear
With a little squat and a few kips and kicks
He knew in a moment it can’t be just one chick
The girls of Crossfit, slowly they came,
And they whistled, and shouted, identified by name:
“Now! Annie, now! Angie, now! Linda, and Lynne,
“On! Mary, on! Nancy, on! Nicole and Karen;
“To the top of the plyo! to the top of the wall!
“Now sprint away! sprint away! sprint away all!”

They were dressed in short shorts, sport bras..such a hoot
And their clothes were covered with chalk, not soot
A medicine ball was flung on each back,
And they looked like a model just showing her rack:
Their eyes – how they twinkled! their muscles, how shiny
Their back cheeks were like mounds, their waists oh so tiny
Their thighs stretched and folded in a squat tempo,
knees kept in great angles, and asses down low
Blisters on tail bones from sit ups were treats
and everyone got up in Turkish beats
They touched the bar with toes to flatten the belly
not thinking at all of a zone with jelly:
No one’s chubby and plump, after AMRAP was done
TABATAS were nothing as they all feel they’ve won
High swings of the bell and twists of the head
Soon clear to everyone they had nothing to dread.
No one spoke not a word, but went straight to their work,
to complete the snatch, the clean and a jerk,
And laying the ego as weaknesses exposed
confidence went down but in seconds rose
They jumped double unders, and hearts beat in sizzle
And away they all flew, like the down of a thistle:
They moaned and exclaimed, feeling better and light
Happy burpees to all, and to all a good fight.

I asked her to write a bit about herself too, by way of Author Profile if you will:

I typically write psychological thrillers and erotic poetry. I have always been physically active but CrossFit is the only one that made me say, “I am obsessed.” I workout at home now using equipments my husband built since I live in a very small mountain town and the nearest box is not the best choice I have. When I am not working out, I could be found teaching third graders and volunteering at a children’s hospital. I keep myself busy as it is a way to manage my obsessive compulsive disorders. I sew, make jewelry, scrapbook, and create paper art.

It’s nice that CrossFit can make connections with people worldwide, despite the fact that I’ll probably never meet many of the people I meet, or speak to in real life.

Featured on CrossFit Community Pages

Colin McNulty Snatch Olympic Lift

You’d think I’d be happy to be featured on the CrossFit Community page here: Colin McNulty Taking a Chance on CrossFit, but I’m not really. Actually I was surprised and humbled when I was asked a few weeks ago if I’d do an interview for the community pages on the main CrossFit site. I am hardly a poster boy for CrossFit, well I don’t think so any way.

But it’s always nice to contribute something and when I asked why I’d been selected, it was in no small part to this blog, which I’ve been running for 5 years now and blogged a lot about the CrossFit WODs and my general experience. And to be honest, I thought it would be cool! 🙂 So after several hours of writing answers to questions and finding suitable photos as requested, I was happy to send off my interview.

It was a couple of weeks later when I got a message that the interview was live on the main site but I confess to being rather disappointed by the end result. The interview I did I think bears little resemblance to the article that appeared on the community page, and there are several factual mistakes that have crept in.

Here are the errors, in order that they appear:

  • “His chronic knee pain made him hesitant to try CrossFit.”It’s not true that I was hesitant to try CrossFit, I did wait a month whilst building up a basic level of fitness, but that had nothing to do with knee pain.
  • “the 41-year-old says” – A minor point, but I’m not 41.
  • “He spoke with CrossFit Manchester coach Karl Steadman” – I didn’t actually say which coach I quoted, in fact I think it was Mark Beck.
  • “A month’s work got me from two rounds to three rounds of 15 reps each” – That should have said: “two rounds of 5 reps each to three rounds of 15 reps each”
  • “coaches nagged McNulty to try the Zone diet” – That makes it sound much worse than it was, I used the words “gentle nagging” which is probably over egging it.
  • “As a personal defense readiness coach, he says his fitness education has come full circle despite his initial skepticism of CrossFit.” – I’m not sure where to start with this sentence?
    • I never said my fitness education had come full circle, I’m not really sure what that means?
    • Nor do I have any understanding what that’s got to do with being a Personal Defense Readiness coach (something that’s not explained in the article at all, despite the main header picture).
    • Nor was I initially skeptical of CrossFit, I’ve no idea where that came from.

Then there’s other issues too, like the links in the article. If information is the main product of the internet, then links are it’s currency. It’s considered good netiquette to credit sources with links, especially if someone has supplied you with content for your site.  I sprinkled the article with appropriate links and as it was this blog that got me this interview, it would seem reasonable to expect a link back to here too.  That didn’t happen and all the links I gave were stripped out of the article.

Whilst I can see why they referenced CrossFit Manchester, I think it’s a bit disingenuous not to even mention the fact that Karl is not longer a coach there, nor mention the fact that my current affiliate is CrossFit 3D.

The photos are a bone of contention too.  I spent some time looking for photo’s that fitted with the article and that were appropriate to submit, but it seems that they’ve mostly been ignored and instead someone has trawled Facebook and ripped photos off there to use. I’m particularly uncomfortable about the photo of the kids being taken and used without any permission being asked.

All in all I’m thoroughly dissatisfied with the whole experience.  Perhaps I’m being naive by expecting more from CrossFit than the normal journalistic twisting of words, or perhaps I’m being over sensitive and should check my ego is still in the bin where it belongs. Perhaps it would be best to let you decide for yourself; here’s my interview in full, as it was originally submitted:

When and why did you start CrossFitting?

It was 5 years ago and I’d just turned 36, was over 15 stone (95kg or 210lbs), had a 43 inch waist and had started getting palpitations sat at my desk at work.  Chatting to a friend of mine online, I said I’d have to start going to a gym, for the first time ever.  I remember he said to me: “Try CrossFit.  6 months of that and you’ll be fitter than 95% of the population” and he was right too!  As serendipity would have it, 2 weeks after first hearing about CrossFit,  I discovered that England’s first ever CrossFit box (CrossFit Manchester) was opening soon, 1 mile from my front door.  In fact I drove past it to take my daughter to school.  Sometimes the universe just sends you a message, and when it does, it’s time to listen.

I went to watch a session first and was completely blown away by the athleticism and functional fitness of the athletes and coaches.  I remember distinctly one moment when a cable had got caught at the top of a wall mounted gymnastic frame.  Just as I was thinking that they’d have to get a Janitor and his mate with a long ladder out, (the) Karl Steadman shinnied up the 20 foot vertical wooden beam to unhook it, with all the nonchalance of a Sunday afternoon walk!   I was literally astounded to see the obvious capabilities and sheer confidence of someone who was completely in command of the faculties nature has given them.

How did you get over the fear of going to CrossFit?

Despite offers to join in, watching that first session was very intimidating, but I had seen something that I wanted: to fully realise my body’s capability. I never imagined I’d be able to do half of the exercises; I’d had knee pain ever since school, undergone 2 sets of consultants and surgery and still suffered severe knee pain nearly every day for approaching 20 years.  Just walking down stairs was a risky business as I’d be in danger of my knee giving way.  I couldn’t kick a football; I’d fall over every time due to the pain.  I had a frank conversation with the coaches, Karl and Mark and explained that box jumps were out, squats were out, burpees were out, in fact I wasn’t really sure what I’d be able to do. But they just nodded knowingly and told me not to worry, everything was scalable and tailorable. I’m sure they’d heard it all before.

“What’s the standard warm up?” I asked. “3 rounds of 10 push ups, 10 sit ups, 10 air squats, 10 pull ups.” was the reply.  “Right,” I said, “I’ll be back when I can do that.”  It took a month of working out in my living room to go from 2 rounds of 5 each of those exercises (which took 26 minutes the first time, yep 26 minutes to do 40 reps!) to 3 rounds of 15 each before I went back for to join in my first session (there was no On Ramp process back then).  By the end of the warm up I was exhausted and ready to go home, but through the support of Karl and Mark, and the other members, I managed to finish a very heavily scaled workout and had done more exercise in that hour than I think I had in the previous 15 years put together.

How did you know you were hooked?

After the first week. My body ached and was sore like I’d never known, but I couldn’t stop talking about CrossFit, much to my wife’s chagrin. She persistently told me I was mad and it all sounded very extreme and dangerous, but I couldn’t get enough of it.  She was right of course (well not about the dangerous bit) to most people CrossFit does look mad and extreme, but once you start actually doing it, and feeling the difference in yourself and your body, it all feels right in a “this is what my body was made for” kind of way.  I truly felt for the first time in my life, I was actually using my body as nature intended.

Who motivated you to start the Zone diet?

It took 6 weeks of gentle nagging before the coaches persuaded me to  try the Zone Diet.  I’d done Atkins before and lost a load of weight, but it had crept back up again once I’d gone back to eating “normally”.  I’d never been able to understand when on days when I was late for work and had to skip breakfast, why I was *less* hungry in the morning?  Now I understand that hunger has nothing to do with the quantity of food in your stomach, and everything to do with an insulin driven blood-sugar low, derived from a carbohydrate fuelled blood-sugar high; it all makes sense and fully fits my own experiences of hunger and weight gain.

I’m all for self experimentation (in a good way!) and so I tried an experiment.  I was working on the Athletic Skill Levels, well level 1 actually the “Well Rounded Beginner” level and one of the targets is the WOD Christine in 15 minutes.  Christine is 3 rounds of: 500m Row, 12 Dead lifts, 21 box jumps (I did 60kg dead lifts and 20” box jumps).  The first time I tried it my time was 19:01, way off the 15 minute target.  Then I started on the Zone Diet.  2 weeks later I tried again, the exact same workout, and got a time of 14:38 a massive 23% improvement.  Now I didn’t get 23% fitter in 2 weeks, so the only explanation is the Zone Diet improved my athleticism.  That was all the motivation I needed to change my eating habits for a life time.  I now describe my diet as 95% Paleo Zone + Dairy.

How long did it take for you to start seeing results?

The easy answer is days.  I could do more on week 2 than I could on week 1. But to be fair I think anyone who comes from zero athletic background and starts doing regular exercise of any kind is going to see quick results. A milestone for me was the ½ year mark though: after 6 months I’d lost 2 stone (13kg or 28lbs), my body fat percentage was down from 30% to 18% and I’d lost a massive 8 inches off my waist.

BUT that pales into insignificance when compared to the real achievement.  After nearly 20 years of nearly daily and severely physically limiting knee pain, within 3 months of starting CrossFit, it had gone entirely!  Not only was the pain gone, I was doing things I’d never thought possible, including heavy squats, box jumps and even Olympic weight lifting.

Why did you start blogging?

Pretty much straight away.  I’d always thought about having a blog but what would I write about?  Well now I finally had something to say, so I started ColinMcNulty.com almost immediately, if for no other reason than to keep a diary of my achievements. What’s really amazing to me though is my little blog gets about 50,000 unique visitors a month now and it increases every month.

Not a lot in the scheme of things perhaps, but I’ve already had a million visits and am getting close to having had a million different people visit my blog! I guess that’s what happens when you write about things that you’re passionate about, like exercise, nutrition, weight lifting and personal safety, among other things.

How has the blog changed you?

Heraclitus, the Greek philosopher said that “Change is the only constant”.  We are constantly changing.  I’ve changed a lot in the last 5 years, both physically and mentally, how much of that I can apportion to the blog, I’m not so sure.

How did you decide to take your CrossFit Journey to the next level (by obtaining your certifications?)

I had never intended on doing a Level 1 Cert as I’d never considered myself coach material, but when Coach Glassman himself came over to run the first ever cert outside of Europe, in my local box a mile from my front door, how could I not attend?!?  It was a privilege and an honour to hear him speak first hand, as well as to buy him a drink in the pub afterwards and shake his hand and say thank you, for his teaching has had a profoundly positive effect on my life.  Since then I’ve also attended the Martin’s CrossFit Kids cert and Burgener’s Olympic Weightlifting cert (Yay Burpees!) as well as BWLA’s Assistant Club Coaches cert.  It was really Olympic weightlifting that got me doing things outside of the box.  I started lifting competitively, which culminated in winning a British Masters Olympic Weight Lifting title in 2010, something I will remember for the rest of my life.

Do you currently teach at a box? If yes, which one and what do you teach?

No, I’ve never had any aspirations to teach in a box.  I enjoy helping people when I can and have coached some friends.  I also judged at the first CrossFit tournament put on by CrossFit Central Manchester, which has now become a major event in the UK CrossFit calendar.  But there are many much better athletes than me, with much more coaching experience. If I were to teach anything CrossFit related, I think I’d specialise in  what I knew best: the Olympic lifts.

What do you love most about teaching others?

This is more relevant to the PDR Self Defence Classes that I do though PDRmanchester.com but can simply be answered with: I love changing people’s lives. I have spent more learning how to coach people in personal safety than I’ve ever charged in fees, but that doesn’t matter.  I’ve taught kids as young as 9 to pensioners, and everyone in between, including one lady who was 6 months pregnant. I have yet to find anyone who wouldn’t recommend it to a friend, women in particular say that after just one day’s course, their confidence doubles, and that’s huge.

Why did you become a Personal Defense Readiness Coach? Any similarities to CrossFit?

I’d looked at martial arts many times over the years, but from a real world self protection perspective, something had always seemed missing about them. I was aware of Tony Blauer and his SPEAR System and it’s general public arm: Personal Defense Readiness, and had watched all the videos, but it was only when Zeb Glover came to Karl Steadman’s new box CrossFit 3D where I was now a member, that my eyes really opened to its simplicity and efficacy.

Not only that, it’s the whole package, not just physical self defence, but personal protection on the psychological level dealing with how to detect and avoid a potentially violent situation, how to defuse a violent confrontation, and only as a last resort defending yourself without needing the hundreds of fancy techniques that other systems expect you to master over years.

Then when I heard that Coach Blauer was coming over to the UK to put on the first PDR Coaches’ cert outside of North America, I had to go.  Karl Steadman and I attended that course and I agree with him when he says that Tony’s teaching changed his life as much as CrossFit has.  It’s a massive eye opener to realise you can avoid being a victim just by the way you act and I’m very excited that Coach Blauer has launched CrossFit Defense which will bring his revolutionary teaching to much more of the CrossFit community than it already has.

What do you love most about the CrossFit Community?

As CrossFit grows, there will be growing pains, and already in the UK there has been some upset and schisms between gyms opening up in the same city as others, it’s inevitable but very sad, not least because it splits the community but also because give CrossFit’s universal applicability, I believe there’s room for dozens of boxes in every city.

But I love that it’s a worldwide CrossFit community, not just a local one. Any CrossFitter can walk into pretty much any box in the world and get a warm welcome.  As I did when I recently holidayed in South Africa and was made very welcome by Danie and Charmain at CrossFit B4C in Johannesburg who asked me to put on a PDR course for them.

I’ll leave it to you to decide just how close the CrossFit Community page article resembles the actual interview and whether I’m being too precious or not. But I know that from now on, I’m going to read CrossFit Community interviews with large pinch of salt on standby.

Would you kill a loved one to end their suffering?

Would you kill a loved one to end their suffering? post image

It’s always very sad when you get that phone call that tells you there’s been a death in the family. Rest in peace auntie Olive, I’ll remember you fondly… BUT not from the last 10 years.

You see my Great Auntie, sister to my beloved grandmother, has been in a care home for the last 10ish years, well her body has at any rate, her mind has been AWOL. I remember her as a vibrant, fiercely independent woman, as was her sister. I remember them caring for my great grandmother and promising each other, if they ever lost their marbles as she had before the end, they would put a black bin bag over each other’s heads and check out with some dignity. Sadly that didn’t happen for either of them.

Both sisters lost their minds in their latter years and ceased to be the people known to their family, and known to me. I visited my grandmother and was aghast at the person I was confronted with, but what made it worse was knowing that had she the self cognition left to understand what was happening to her, she would have been mortally ashamed. I didn’t want to remember her that way, and I know she wouldn’t have wanted me to see her dishevelled, unkempt and incapable of recognising me or holding a sane conversation.

Whilst I feel some shame about it, this is the reason I haven’t visited my great aunt in 10 years: I know she wouldn’t have wanted me to; it would have upset me; and it would have spoilt the memory I have of her. Maybe some would say that’s a cop out and an excuse, but I have thought long and hard many times in the last 10 years about a visit, and always decided against it on those grounds.

Strokes and other old age ailments rob our elderly relatives of dignity and condemn them to a long and suffering death. Indeed hours before my auntie Olive died, I’d been told that they were planning to withdraw all medicine and take her to a palliative care home; a check out hotel effectively. How nice that the best the medical profession could come up with would be to provide her with a painful, uncomfortable, lingering death at the end of her 10 year journey to the grave.

Put a dog to sleepI have to ask myself: what’s the point of it? Why keep someone alive who has next to no quality of life? As my father in law used to say: “You wouldn’t let an animal suffer like this, so why would you let a person?” What has auntie Olive gained or achieved in the last 10 years? Every time I asked people how she was, I was always told that she basically wasn’t there and didn’t recognise visitors. It’s so very very sad.

So what’s the alternative? Euthanasia? Why not, we put animals “to sleep” to use the common euphemism. And believe me, if you’ve ever had to do it, that’s no easy decision. As a grown man I’ve never cried more than when I’ve had to take a living pet to the vet, and come out with a dead one. But you do it, you make that most difficult of choices, not for you, but for the pet you love dearly. You decide that when the time comes, it’s the last loving gift you can give, the gift of rest from a painful, meaningless, inexorable slide into death.

But most crucially, it’s done at a time of your choosing. When you can be with them, with other loved ones, to comfort and hold them in the last moments. After all, who here wants to die alone? Given a choice, wouldn’t we all want to die at a time of our choosing, with our family and friends at our side, with the opportunity to say goodbye one last time?

For 5 years Ted, my father in law declined, getting more and more infirm and paranoid. I remember well the look of deep embarrassment in his eyes after I’d helped him to the commode and then had to bend down to pull his pyjama bottoms up as he could no longer do it himself. I remember many times getting the “You’d better come quick” phone call and dropping everything to rush the 100 miles to his hospital bedside, the all night vigils that followed, the waiting for days, just sitting watching the heart rate monitor wondering if the next beep would be the last and then what you’d do if it was. Would you rush out to find a nurse or just sit there and let nature finally give him the peace he deserved? Every time we left, I wondered if that was the last goodbye?

My mother in law and sister in law would keep near constant watch over him, taking it in shifts to be at his bedside, especially when he was in hospital. My mother in law especially was adamant that someone would be with him when he finally went. This went on for years. In the end, he died alone anyway despite them being in the hospital at the time; they’d just popped to buy a sandwich and returned after 1/2 an hour to discover he’d passed away. I sometimes wonder if it was Ted’s last joke, because if anyone would have seen the ironic humour in that, he would have. I loved that not so old man, but hated seeing him in his declining years, and worried that my mother in law would feel guilty that she wasn’t there for him at the end, I know my wife did, and that is so sad for all involved.

Terry Pratchett Alzheimer's Disease EuthanasiaIt seems to me then, that thinking about what’s best for the terminally ill relative, and what’s best for their family, is to die with dignity and a minimum of pain and discomfort, at a time of their choosing, with the people around them that they love. This is why the Swiss euthanasia clinic Dignitas has become a world wide name, with some very famous people signing up for its services, like the world famous author Sir Terry Pratchett, author of the Discworld series of books, who has been diagnosed with Alzheimer’s disease.

As adults we have almost complete control of our lives: where we live, what we do for a career, what we do for leisure, who we marry (mostly!), what we eat, how much exercise we get, what kind of car we drive etc etc, and yet as soon as it comes to a choice about death, oh no, the state intervenes and says: “You shall not think about how to die. You shall not think about ending your life. And if you do, you’re mentally ill and we’ll take your freedom to choose away.” In a “free” society, it’s an weird anomaly.

So why does the government take this stance? It all comes down to religion. As a nominally Christian country, the state imposes the Christian belief that life is sacrosanct, and only God can choose when to end it. Well that’s fine. I completely respect people’s freedom to choose a religion that suits them, and their right to practice their religion without impediment, providing doing so doesn’t impede the freedom of others to follow a different religion.

That’s reasonable isn’t it? You do your thing, and I’ll do mine. That’s what being free is all about. But what when your religious choices impact my religious choices? What happens when your religious belief is deemed to be more important then mine? If you believe that all men should wear a head covering as some orthodox Jews do, does that mean that men who aren’t Jews should be force to? Most reasonable (non-Jews) would say not. And what if you believe that you should give 10% of your earnings as a tithe to the church? Should all people be force to do that? Most again would say not. It’s a choice.

So why is it that because your religion says people should not want to die and shouldn’t be allowed to kill themselves, that that belief should be imposed on those that want the freedom to determine their own destiny? In fact it’s worse than that, it’s not just illegal to commit suicide, it’s illegal to help someone kill themselves. There have even been organisations like the Hemlock Society setup to give people information on how to die with dignity. There are sites you can find on how to hang yourself for example, all illegal under UK law I believe anyway.

Nitrogen - Helium Suicide Hood Bag KitI remember a story last year about someone being prosecuted in the UK for selling suicide bag kits, or “Exit bags” as they are called, which are just plastic bags you put over your head, but fill with an inert gas like nitrogen or helium to bypass the body’s natural anti-asphyxiation response. You just breath normally until you lose consciousness and then die in your sleep. It’s the quick, painless, and pretty much certain checkout method of choice apparently.

Now the interesting thing is that asphyxiation by breathing nitrogen is apparently pretty hard to detect, after all, 80% of the air we breath is nitrogen anyway. This could even be used as a method to kill someone without detection perhaps. What if you decided that an elderly relative would be better off leaving this mortal existence and decided to hurry them along a bit with said nitrogen filled suicide hood? Of course now you’ve stepped over a line and you’re a murderer, however well intentioned you may have been.

But, and here’s the rub, most old people I’ve had the pleasure to know, know one thing for certain: they don’t want to be a burden. I guess there comes a time in your life when you realise that you’ve had the best of your innings and it’s time to leave the world to the next generation. Particularly if you’re in ill health, have failing funding, on a low pension, perhaps your life partner has already passed away and you’re lonely. Maybe your family have mostly moved away and don’t visit as often as you’d like.

If you were in a situation like that, feeling low and depressed but putting on a brave face perhaps, and a family member came along and suggested to you that perhaps it was time to “move on”, maybe you’d listen. Perhaps that family member wanted a cash injection, and had an eye for their inheritance from your estate, mostly from the proceeds from selling your house, and didn’t want it frittered away on nursing home fees. Perhaps you weren’t ready to go just yet but were made to feel unwanted, un-needed, unloved, and a “burden”, and pressure was applied to make you consider suicide. Violence might be used, whether physical of psychological. I can imagine it wouldn’t take too much to convince a frail old relative, against their better judgement, that it was time to check out.

And there you have it, the simple reason that euthanasia is currently illegal in most of the world, because of the chance that it might be abused. That people might be coerced. Maybe even that people could be surreptitiously murdered, perhaps even by a medical professional like Dr Harold Shipman, possibly the UK’s worst ever serial killer. And so elderly people in their hundreds of thousands are left to suffer and rot in so called “care” homes, slowly waiting for an ever increasingly emotionally and physically agonising death, because of the fear of abuse that allowing euthanasia will bring.

Do I think the system would be abused? For sure it will, just like humans abuse every system and environment they find themselves in. Do I think that by far the greater harm is done by not allowing it? For sure it is. Do I think that we humans can be pretty clever when we put our minds to it, and can devise a system that installs suitable safeguards for 99.9% of cases? Absolutely we can. The Swiss seem to have managed it already in fact, so it can be done.

Euthanasia is a very emotional and touchy subject, and rightly so, because death is something that will come to us all. Yes me, and even you reading this now! Let us hope that by the time it comes to you and me, we have the right to choose when and where and with whom we will die. I for one don’t intend to wither in a nursing home for years, begging for the end and emotionally scaring my child in the process.

Goodbye auntie Olive, I’m sorry I didn’t visit you but I know I’ll remember you how you’d have wanted me too.

Why I Love Teaching Self Defence

Colin McNulty and some Manchester Self Defence students

I love teaching Tony Blauer’s Personal Defense Readiness self defence to people through PDR Manchester, and this proves why: I’ve just collated the feedback forms from the Home Ed kids and parents course I ran a few weeks ago, here are the average scores from 8 feedback forms returned:

  • Confidence Increase: 271% <– That is huge!
  • Course Content score: 9.6 / 10
  • Course Value score: 9.9
  • Coach’s score: 10.0 *blush*

And to go with it, here are some of the comments:

  • “It has greatly increased my confidence. I was nervous but Colin was an excellent tutor and made everyone feel at ease. I never would have dreamed in a million years that myself and girls would willingly participate in this, so I’m extremely proud of us. It could have been very scary, tackling a man, in that intimidating suit and in front of an audience as well, but Colin made everyone feel at ease. I think the class was very empowering too. Thank you.” – Linda Kennedy
  • “It is really good and helps educate you against the big bad world” – Josie, aged 13
  • “The best bit about the course was feeling more self confident and *getting to attack Colin*” – Perren, aged 11
  • “The course is very helpful and Colin is an excellent coach” – Sue Pamp
  • “The best part was being able to have the knowledge I can now handle these situations. I would highly recommend it.” – Leira, aged 13

🙂

You can see more pictures from the course on the PDR Manchester Facebook page here.
