Are there no hikes are available to you? No mountain peaks you could crest and see spectacular views? Camp under the stars? No nearby lakes you could go for a swim in? Take a kayak on? No ocean where you could learn to surf? No rocks nearby you could climb on? No forests into which you could disappear for an hour or two to lose yourself? Heck, no possibility to live close enough to work to commute by bike?

I really, REALLY do not understand people whose idea of staying fit begins and ends with gyms/treadmills. Hell, treadmills would make me want to shoot myself, so you have my sympathies there. But I've been outside running in sub zero temperatures, and walked on exposed peaks under the hottest sun, biked in absolutely torrential downpours. All of what you're saying sounds like excusitis to me, sorry.

I was never interested in a single thing you listed in your first paragraph... it's incredibly boring for me. I understand it's fun for a lot of people, for me it's the opposite. I'd literally rather do mildly annoying chores. But hey, I can lose myself for days on end building circuits or reverse engineering things.

During my university days, I sometimes would do stuff you suggested with friends (a little bit), but for me it was just to hang out with them. Ultimately, I was always happy when the "main activity" ended and we found ourselves in a café or bar talking afterwards.

I love nature and want to preserve it, but I choose to enjoy it by sitting in it with friends, or reading a book.

I'm curious what is the net tradeoff between all those activities you listed in which you're in the sun and not being in the sun. IIRC the sun actively ages you AFAIK and this topic is about trying to not age.
