Get your calcium...

Here is an abstract of the article There is lots to be learned yet about osteoporosis. Last summer, Reuters had a summary of a study reported in "Lancet" that not all of the problem of hip
fractures can be predicted strictly by bone density. Certain activities, like rowing & cycling seemed to specifically strengthen the neck of the femur, reducing the incidence of fractures. Unfortunately, Reuters has dropped the link so it will take me a while to get a link to the original article. Remember, science can not keep up to even a slow cyclist going uphill in a wind and ice storm. The way bone remodels, heals, and degenerates is very complicated and won't be fully understood any time soon. Get your calcium, get your exercise and don't be afraid of your bike.
