From a response of mine to a drinking buddy who commented he doesn't think he'll be able to party at all in 20 years:

Dude, It will be like our Dads did - sipping on a fav drink at functions and not getting too wild.

That's when our kids start to learn from observation "what Dad's drink is". Which they'll think has always been our drink (because we don't tell them how much we actually got shitfaced back in our day). Then when oure kids get older, start cutting back, and settling on that one thing they know they like and doesn't tear them up, then they realize the generational chain of it all.

Circle of life.

I'm proud of that one.
