Yep, that's pretty close to one of my motivations as well. I have a son with special needs, he's only 11 now, and if I'm going to be there for him long term, I have to do what I can. The only time I've been down was back in '06 when I had appendicitis and had to have it removed. It took about two months for my abdomen to recover, and I learned a very valuable lesson then: If you don't have your health, you don't have anything. You mention prescriptions. While I don't want to jinx it, I am one of the few people I know my age who doesn't have any prescriptions. I have some friends who take more pills than Elvis did, and that just scares the crap out of me. What will they do when SHTF? How will they manage when they can't get those because either society has collapsed, or they've been excluded from it for some reason? Being in shape makes it easier to be sort of "self contained" and independent. It's a type of freedom, and one I won't be without.
