I hike, and often when I hike I also collect edible plants. It's usually enough to make a salad at home, but when I grew up we'd collect massive quantities, enough to preserve and help see us through the winter. I practice map reading and orientation skills, and always volunteer to build a fire for picnics & campouts, using the same tools I would usually carry.

Beyond that, I'll sporadically be involved in martial arts or I'll go shooting. I read books and articles, and recently have looked into taking CERT classes. Like most people, I really could be doing more.
