I've talked about Frank Forencich - and his book Play as if your Life depends on it - before. His books are great for ripping through the science and getting to the heart of having fun moving.
Here, Frank Forencich gives a live presentation on "A Body Centered Curriculum", subtitled "The Primate's Predicament". In the presentation he reviews the current state of modern health - while this seems like a bleak picture, he then offers suggestions on how to improve our bodies, minds, and culture(s) by doing a slight mind-set slide. Absolutely superb.
