I seem to have a lot of time on my hands now (post retirement). I'm doing some volunteering but I'm looking for an interesting hobby I can pick up and put down where I can use up some of this time. I cook, read, sew etc, but I'm looking for something more. Hopefully that doesn't cost a lot to get going.
I have spent a fair bit of time on free MOOCs (massive open online courses) - there are a lot out there, and of course I could do another one - highly recommended.
It would be interesting to see what some of your more unusual hobbies are. And, hopefully something will take my fancy.
