so Crankin, or anyone else, how did you find out that you had osteopenia? What started you tracking it?

I'm interested after reading here and other places about the need to keep up high-impact exercise, especially since I know I walk and hike much much less now than 10 years ago, and bike much more. I also don't drink milk, but do take a calcium supplement daily. Is this something I should be checking out regularly as I get older?
