GUEST, I'm sure men did the study, so I suppose it must pass muster before you accept the findings, but it is well documented that women from Northern European countries, Scandinavia in particular, are more likely to develop osteoparosis. That doesn't mean that every Scandinavian will develop it. My mother and her oldest sister did, but the middle sister doesn't appear to have. She's also the sister, about age 82 now, who swims and works out regularly.
