Skiing, as far as I know, is more than going down a slope. It is
full of complications, such as the wedge, French fry position, pole
plant, and the up-and-down weight shifting.
You can hurt yourself in skiing. One of the most common ones is the
old chairlift fall down injury. It isn't much of an injury; the most
likely one is getting a twisted ankle, mostly. Besides, you'll probably
lose your skis.
From my experiences, however, skiing is very fun. The first time, I
fell down at almost every slalom that I made. But then I got better.
When I went down the really easy slope for the last time...it was the
easiest thing I ever did.
