(Medical College of Georgia at Augusta University) The force gravity and physical activity put on our bones causes tiny tears in the membranes of the tiny cells that enable us to make or break down bone, scientists say.While that may sound bad, it's actually a key piece of how the force we put on our bones helps keep them strong, they report in the Journal of Orthopaedic Research.
