JEEBUS...
I'm about to turn 48 and skiing as well as ever. Of course, my standard activities don't include big drops or hammering lots of bumps. Still, if you want to keep skiing for a long time just accept that big crashes and big drops aren't as easy to recover from when you're not 25 anymore. It's not so bad; there are lots of cool things to do on skis besides huck.
Best thing I ever did for my body was buy a house that has a hot tub. Drinking wine in the tub after big days really speeds the recovery, along with lots of water intake.
Be REALLY careful about taking NSAIDs when you're drinking... I'm no doctor but I am afraid of kidney failure. I don't think Ibuprofen and booze is a good combination. I KNOW Tylenol and booze is a no no.
Fred Beckey rules! I met him climbing over 20 years ago and he was already old then.
