Hey Gen x, I'm about to turn 46, how should I start preparing for that downhill slope that is 50?

Excercise, save $, don't retire too soon!

grow a pony tail, buy a sports car, date an 18 year old

Practice walking into a room then try and recall what on earth you went there for

I didn't feel a downhill slope until 51 or 52. Stretch, walk, eat healthy, fall in love, seek nature and hydrate.

stock up on aspirin

Take lots of naps. You'll need the energy to stay up past 8p.
