I have a lot of hobbies, and I decided a while ago to trim my time down to wetshaving and RC airplanes.
Tinkering with electronics will be reserved for an "as needed" basis, like when something in my smart-home setup stops working, and I sold most of my woodworking stuff.
Unfortunately, RC airplanes and shaving do nothing for my physical fitness, and I've always had an interest in biking. I have a nice road bike, but I refuse to ride it on actual roads so I don't get run over, and having to put the bike in my car to drive to the nearest rail-trail isn't much fun.
I have a mountain bike from 2004 (20 years old!) which has a steel frame, a hard tail, and 26" wheels. I've tried riding it on the trails behind my house, but it doesn't quite cut the mustard. Modern mountain bikes have changed A LOT, and I've wanted one for the past few years...
So I got one. It has full suspension, an aluminum alloy frame, 29" wheels, a dropper post, and geometry that's "slacked out" as the kids say.
I've been on 2 rides so far, and already feeling stronger. It's so much more fun than the old bike, and we're lucky to have numerous trails to ride around here. I have a small trail system right in my back yard, or I can throw the bike in my car (I know I said I don't like doing that, but it's worth it if it's fun) and have access to probably 30 miles of different trails within a 10 minute drive.
I'm stoked! Gnarly!
