Ask HN: What did you do after you turned 40 that you don't regret?

I wouldn't recommend this without reservations, but I passed my bike test at 40 and got a 1 litre adventure sport motorcycle.

I'd ridden bikes in my youth and have been a professional driver for most of my life. Knowing how roads work, how dangerous all the other fools on them are, and being used to the hazards on UK roads, I started off slow. Every car driver is a "didn't see you, mate" waiting to happen.

The freedom and joy of riding through North Yorkshire, the beauty of the place, the days out in the sun, and the people you speak to make it a massive thing in my life that I wish I could do more of.

At 51 (bit overdue for a mid-life crisis), went back to university to do a PhD and teach.

Get someone would say, have a child!

Started playing with oldies musicians after the music I grew up with got far enough out-of-date.

Sold everything. Relocated from north Europe to a tropical island in Thailand.

Started swimming.

Kegels. Can do them in meetings.

Kettlebells
