Skiiing? Please do explain

I take it means downhill. Not cross country which to me seems safe, apart from causing asthma in Norwegians for some reason... But downhill version involves going relatively fast or really fast with some small change for sudden stop, which in very few cases is safe.

Skiing becomes incredibly dangerous once you get into like…your 40s and beyond unless you have been doing it pretty consistently your whole life. And even then it’s still very dangerous. High speeds, downhill, crashes are serious.

It’s a sport many people step away from for long periods of time (I.e. the muscles aren’t in shape and they're rusty) and it demands a lot unless you’re sticking to bunny slopes.
