How do you stay (somewhat) healthy?
mattiss: Get hobbies that correspond to the lifestyle you want to lead. If you aren't having fun, you won't keep with it.As a corollary, if you have an active hobby and any sort of drive to be good at it, you will train yourself as such. So if you take up say rock climbing and like it, then you will get lots of exercise as a direct result of climbing, and lots more to train yourself to get better.
