I've lifted weights off-and-on since highschool (the "off" was usually long enough to lose all gains), but after a couple years' hiatus, this summer I've taken a new interest in traditional functional strength feats like natural stone lifting (as featured in competitive strongman events). Currently this training occupies more time than other interests.
Also reading (fond of medieval lit, and some beloved early/mid 20th century Christian British authors), traditional archery (switched from wheel-bow to trad many years ago), hiking/camping/canoeing, armchair theology/philosophy/liturgics, etc.
At one point, regenerative gardening was my life, but I've since moved to a property ill-suited to that and haven't figured it out here yet.
I tried making a few fly rods, but am the world's most unsuccessful fly fisherman and apart from an annual token attempt I've given up on it.
I used to bow hunt most years, but I haven't been out in a few.
In a previous life I was part of a whisk(e)y tasting group, and was also semi-serious about collecting big beers to age (but I almost never drink anymore as it doesn't comport well with some physical goals -- I now drink only on special occasions).
I also have a theoretical interest in old clockworks and automatic watches, but that's a rich man's hobby and I have just a few cheapies.
A few sit in potentia:
I've started to set up a bit of a wood shop in my garage, but it's still a mess and I haven't done much yet. Would love to learn more there.
I keep wanting to try bee keeping, but haven't squeezed the trigger yet.
I also keep wanting to learn the octave mandolin (an octave lower than standard mandolin, similar size as tenor banjo and same tuning), but not sure if I'll ever really get to that one.
And of course pipes and pipe smoking.
