There are different factors that go into making bones strong as we are discovering through advancements in technology, observation, research and testing in addition to information discovered in the past although "buried under the rug".
We all know that lack of use in a living thing can tend to bring upon decay. Many have found that this is to be the case.
Additionally others have found factors such as nutrition habits: Good nutrition habits versus bad nutrition habits - are an important factor to having strong bones. But what are these nutrition needed good nutrition habits and what are these bad habits we need to vanquish?
Bone strength involves two primary factors: The hardness of the bone and the flexibility of the bone. We want to make our bones stronger but not rigid so they shatter but be able to withstand impact.
In order to optimize bone strength one has to take it on as a challenge taking responsibility for one's own health. Relying on someone else to fix your problems may not be the best thing especially if that thing is some sort of magic quick-fix solution.
