Quoted message said:Remember, there were once people (backed up, no doubt, by the results described in peer reviewed
scholarly journals) who claimed it was safer to be thrown clear of a car in a smash than be
strapped in by seatbelts.
Remember there were once people who compared the fatality rates in countries with and without sealt
belt laws and found them to be the same. Obviously that couldn't be right, so that data was buried.
Amazingly, when the UK introduced sealt belt legislation - driver fatalities stayed the same! But
there was a substantial rise in pedestrian, cyclist and rear-seat passenger fatalities.
Quoted message said:If you ride a bicycle for long enough, well, statistically, you're going to take falls, and take a
bad fall sometime or other. If you don't think so, you are either or both of a) lucky b) a fool.
There is no inevitability about it.
Quoted message said:Collar-bones heal. Scafoids (most times) heal. Broken arms, dislocated shoulders, skin over
ankles, knees, hips, back, arms and hands all heal. Acquired brain injuries don't heal.
And acquired brain injuries - amazingly - are mostly caused by crashes well outside the design
envelope of hlemets, and by mechanisms which helmets do nothing to mitigate.
Quoted message said:A bicycle helmet (probably) didn't save my life, nor did it stop me from getting smashed and
ripped up really badly, which generally happens when you hit the asphalt at 60 kph. But it did
mean I can still walk, talk, ride a bicycle.
Or not. Maybe it was your Mk. 1 Skull which did the job. That would be a reasonable assumption,
given that people not wearing helmets also often survive without significant injury. That's the
problem with helmet-saved-my-life anecdotes, they always attribute the outcome solely to helmets.
Why? Lids are designed for straight impacts at speeds up to about 12mph. Why should we assume that
they work in glancing or rotational impacts at higher speeds? And what about the people who die when
wearing helmets? And the people who don't die when not wearing helmets?
At the population level it's not possible to proive that helmets have any effect on brain injury.
And even then, most cyclists who die of head injury turn out to have other mortal injuries as well.
The case for helmets really is not half as cut-and-dried as the Liddites would like us to believe.
The only absolutely repeatable effect of helmet legislation is a substantial drop in cycling. And
the major determinant of risk for cyclists appears to be the number of cyclists - the more people
cycle, the safer it gets.
Quoted message said:And same goes for all the many less major falls before and after - any a hit to my bare head, on
pavement, car, trail or whatever, might have meant a concussion, a subdural haemorrhage, or worse.
I haven't had to find this out, though. Because... well, you know why.
Why? I have had several crashes with and without helmets and there was no noticeable difference in
outcomes. The most serious head injury I ever had was going through a low doorway. Should we have
compulsory helmets in old buildings? Or only for tall people?
