I've got to start remembering to take a vitamin supplement with calcium every day, not just 3 or 4 times a month when I happen to think of it. My grandmother and great-grandmother had crippling and disfiguring osteoporosis by the time they were in their 60s, but my mother has avoided it into her mid-70s by taking calcium and drinking several glasses of milk a day. I don't really want that much milk, but I should try to have some, at least. I'm only 5'3", and I can't afford to lose much height. Some beginner yoga wouldn't hurt, either.
