Beekeeping, rowing, swimming, knitting, photography, gardening. I also do quite a bit of tech stuff, and some sewing and baking. None of it is for income, though I have been paid for a few photos.

Beekeeping is far and away the most absorbing and interesting hobby I’ve ever had. Where I live there are very active local associations that support learning and hold social events. The national association organises courses at all levels. A government department sends out bee inspectors to check for disease; great support and another learning opportunity.

If you want to, you can make good money from selling honey. It’s a lot of hard work, but really enjoyable.
