Yes - standup comedy. I’m 47. Started 2 years ago, background mostly “nerdy” and not hyper social. Have done some paid gigs and performed for crowds of up to 150.

And at 38 learnt rock climbing ... got quite far with that until was stopped by an injury.

Also more recently podcasting and literally today Adobe Audition. More nerdy I guess but still.

Somehow programming is a good career to have a mindset of “I can learn anything”. The only thing I really think speaks against age when it comes to learning new things is your ability to dedicate time to get deep into whatever you’re learning. Job, family and other commitments etc can make it harder but if you’re willing to sacrifice some Netflix time many things become possible. Perhaps the other point is motivation - I won’t “waste time” learning things if I’m not highly motivated to do it - perhaps it’s an awareness that time is more precious now, I don’t know.
