I typically spend my leisure time
Anything that I want to do. To be able to simply take part in anything that piques my curiosity. For a more specific answer, I enjoy archery. I make my own bows and shoot nearly daily. The pursuit of mastery of the craft and sport calms and relaxes me; gives me something small to think about when there are empty periods of time. I also enjoy bicycling, swimming at a local creek, and scuba diving (though I haven't gone in a few years).
