I'm a huge advocate of gardening. It gets you outdoors and active, gives a sense of achievement, you learn and improve over time, it's popular enough that you can get involved in a community, if you're growing veg it promotes healthy eating.
You... sound like my mother. She's an incredible woman, but christ, no I'm not gonna go climb a tree right now and chop off the top branches, I'm in the middle of a Minetest marathon
I know you didn't really mean it literally but just to reiterate as others have done for other suggestions in this thread, this is very much an "if it works for you" sort of thing and definitely shouldn't be mandatory. I fucking hate gardening with a passion, I want absolutely nothing to do with it, though it's clearly very beneficial to others.
