Boosting your brain and body is the theme of today's show, where I've plucked three of the best guests (different format alert) when they go big-time in depth. Their subjects could be dry, but they are so good and knowledgeable that they make it entertaining.  I love depth, and that's why I've called it the smartest ways to boost brain and body. Dave Asprey on Stem Cells (brain and body) Dr Pompa on Water (brain and body) Todd White on Alcohol (brain and body) Enjoy getting the old grey matter working hard.
