[music playing] narrator: some have describedthe skeletal system as the infrastructure of the humanbody, providing a rigid framework that offers protectionand support, as well as attachment sites for thetendons and muscles that are essential for locomotion. the skeletal system is comprisedof 206 bones, each of which is formed through aprocess known as ossification. bone development and remodelingtakes place on a continual basis, from theprenatal period and early childhood through adulthood, aswell as during the healing process that occurs followingbone fractures. ossification can take one oftwo forms, depending on the type of bone that is forming. in the case of flat bones,like those of the ribs, scapula, pelvis, and skull, theossification process is known as intramembranousossification. the process is initiated bymesenchymal stem cells, which are cells that have yet tobe differentiated into a particular cell type. eventually, centrally locatedmesenchymal cells within the embryoni...

this session is on natural wonders, and the bigger conference is on the pursuit of happiness. i want to try to combine them all, because to me, healing is really the ultimate natural wonder. your body has a remarkable capacity to begin healing itself, and much more quickly than people had once realized, if you simply stop doing what’s causing the problem. and so, really, so much of what we do in medicine and life in general is focused on mopping up the floor without also turning off the faucet. i love doing this work, because it really gives many people new hope and new choices that they didn’t have before, and it allows us to talk about things that -- not just diet, but that happiness is not -- we're talking about the pursuit of happiness, but when you really look at all the spiritual traditions, what aldous huxley called the "perennial wisdom," when you get past the named and forms and rituals that really divide people, it’s really about -- our nature is to be...
