Poster: A snowHead

abc, interesting argument. But it assumes that normalising per year is the proper way of doing it. What about normalising per hour or per mile? Of course there is evidence on the effectiveness of hip-protectors in the frail elderly reducing fractures (body armour really!).
I would choose the risk per hour exposure as the correct method of comparison, and I suspect that skiing in the trees/avalanche territory is a higher risk to my brain per hour than walking or driving - especially now we have ABS, Airbags, Crumple zones etc etc.
It remains a personal choice however.

veeeight, I very much doubt any air bags are speed activated. They all use accelerometers as far as I'm aware. |
That's what I said. I never said that deployment is speed activated. But I added that the speed figure itself is used as one of the many factors in the algorithm for dual-stage deployment.

Well, the person's real but it's just a made up name, see?

No, I didn't assume it's the "proper" way of normalizing it. It's ONE WAY to normalizing it and it reflects the overall chance of banging one's head.
It has certain drawbacks, one of which being the frequency of skiing vs walking may differ amoung population. For example, an someone living in Jacksonville Wyoming probably don't walk much at all (just drive from door to door) and ski 2 days a week for a good 6 month out of a year. While a Londoner may walk a fair amount and only ski 6 days a year. Though it could potentially lead to interesting conclusion such as a Jacksonvill resident should wear a helmet skiing while a Londoner should wear a helmet in town.

This is what I wrote earlier:

Per skier per unit time, skiing could quite possibly be more dangerous than walking.

Anyway, snowHeads is much more fun if you do.

Here I sit at my desk, reading this with my bike helmet within reach and the thought stricks me - it is an undeniable fact that I would be safer and better protected wearing that helmet right now...........
