Is it becoming an expert in any hobby or just that one? Because I have a couple hobbies I’m an expert in, one I am two heartbeats away from being the world authority in, and I don’t think it’s helped my brain.
Are those heartbeats someone else’s and are they now dead? Also what hobby? This peaked my interest a lot.
yes they are other peoples, and no they are not yet dead.

I don’t know, but when I started recognizing birds by sound I noticed it was working as a constant mindfulness exercise whenever I went outside. You’re training to be aware of your surroundings. I suppose mindfulness has similar positive effects on the brain?

Then I’d say any hobby that encourages mindfulness has a positive effect on your brain?

I was folding laundry inside once and heard a Nerf Turbo Screamer football being thrown outside. It was a red tailed hawk in a tree a few doors down.
Do those hobbies include spending a lot of time in nature outdoors? An activity that has also been shown greatly improves mental health?
not the ones i’m good at no
