My hobby pastimes have been gradually describing an interesting arc, starting from essentially the oldest human passtimes and advancing forward through time. I really need to stop and revisit flintknapping though. Wild edibles are a bit of a dice roll, and manual firemaking is actually quite a workout. Weaving is almost infinite in depth, and has a particular attraction to programmers for its historical connections. Woodworking and pottery are big wins, for people who are technical but want to get out of their own head. To quote Gibson:

"If they think you're crude, go technical; if they think you're technical, go crude. I'm a very technical boy. So I decided to get as crude as possible."

You can get very technical indeed in some of humanity's oldest industries.
