Now, my brother the statistician is going to probably give me a hard time for this generalization, but if you flip that around, that rate is one injury per 454 skiers per day, or one injury per 454 days of risk exposure. Which got me to thinking...
I'm an anal-retentive engineer and have tracked every day I have skied since 1996 (19 years of data). That year, I got a recording altimeter watch, and I've just been logging my info ever since. Now, I first started skiing in 1978 (on borrowed equipment from a friend of mine, through a University ski club that let me learn dirt cheap). So I'm missing 18 years of data, or half of my ski years. But I am certain that:
- I only got ~10 days a year from in my university years from 78-81, virtually all of which were in lessons;
- I probably only got 5 days a year from 81-84 (before I moved to Edmonton);
- I hardly skied at all from 84-89 -- perhaps 2 days per year -- due to living in Edmonton (too far from the mountains to ski much), work and getting married;
- I didn't ski at all from Nov 90 to Nov 92, since I was living in Victoria;
- I was so broke from 92-95 that I was lucky to get 2 days in per year.
- On logged day 178 (Day 250?) I crashed on ice at Big White and broke a rib in my back. No lost time, no ski patrol, but an accident nonetheless.
- On logged day 540 (Day 610?) I broke my leg.
