There is a very, as in VERY, determined helmet lobby in the UK.
I've posted this before but it's worth a re-post.
I was working in my shed when I pulled a pair of pedals from a hook under the shelf. They were tied together and the second one snagged and then sprung free, catching me above the eyebrow. It beld profusely and within seconds I was blinded by blood running into both eyes.
I felt my way into the house and found the phoned my wife, who was out shopping, and she came home and ran me to the hospital.
The A&E nurse treated me, super-gluing the gash above my eyes and washing off the blood, then
filled in an accident form.
Q. How did it happen?
A. I hit my head with a cycle pedal.
Q. Were you wearing a helmet?
A. No! I was in my shed and pulled it onto my head!
Nurse fills in form with 'Cycling accident-No helmet.'
Me. Hang on it wasn't a cycling accident, the pedal wasn't on a bike, I was in my shed and why the **** should I wear a cycling helmet in the shed?
The row escalates and the A&E Sister turns up in the cubicle.
Sister. What's the problem?
Nurse. He hit his head with a bike pedal.
Sister, That's a cycling accident, was he wearing a helmet?
Me. I was in my shed why should I wear a helmet???
etc. etc. etc.
End result? They put it down as a head injury due to cycling and I was not wearing a helmet!
Does anyone think that if I'd pulled a carburettor onto my head it would have been a motoring accident, with no seatbelt? Or pulling an aircraft radar unit onto my head it would have been an air accident?
Theory.
The statistics are being fiddled and the helmet lobby are part of it.
Conclusion.
That's something that my experience reinforces and the net result has been that I no longer wear a helmet. What's more, I'm quite prepared to ignore any future law mandating helmets. If they want to cheat the statistics, I'm up for challenging the law.
