Doing the right things for healthy bones

There are some things that we take for granted until when something happens. Last week a friend of mine lost a sister due to an illness that was affecting the bones. What was more perplexing is the fact that all other diseases including cancer were ruled out, but this lady suffered pain in her bones until her death. Some things are ignored until when you hear a person has suffered due to it. How many of us think about their bones at least even once a week? How many of us ever think of eating some special foods so that once in a while the bones get all the supplements they need? Your guess is as good as mine
