For a while I used to chaperone elementary school ski trips (back when my daughters were part of the group). When (not if) the kids fell I used to think about what would have broken if I had fallen the same way. Of course the kids were fine, and would jump back up and continue down the hill.
Largely for this reason I have generally recommended that people start skiing when their age is still in single digits.
However, I was thinking that I might want a trip to Courchevel in a few years.
