Hmmmm... This is a little scary.

I'm only 27, but I worry about bone density because I've been on Depo Provera for gee, around 4 years now and haven't found anything I want to replace it with yet. Since it depresses estrogen levels, it can allow bone loss to accelerate. Some docs are more concerned about this than others, but every now and then someone tries to persuade me to change birth control methods.

I take 1,200 mg calcium supplement daily. I also try -- usually successfully -- to get 2-3 servings of dairy daily. This is a good idea because it's generally thought that calcium in food is absorbed better than calcium in supplements...

I DO run at least a couple of times per week. I'm trying out the idea of running a marathon next May, so once I finish midterms (!!!) (oh yeah, I took serious time away from school working and now I'm finishing my bachelor's as an old lady) hopefully I'll be stepping that up significantly. I guess the message here is I really need to start weight training. I've done it in the past but frankly, not recently...
