I saw this mentioned by Frank Forencich and it looks interesting, so I ordered the book (extract here).
The author's blog has some nice stuff.
In Spark, John J. Ratey, MD, takes the listener on a fascinating journey through the mind-body connection, presenting startling new research to prove that exercise is truly the best defense against everything from mood disorders to ADHD to addiction to menopause to Alzheimer's. He explains that the brain works just as muscles do-growing with use, withering with inactivity-and shows why getting your heart and lungs pumping can mean the difference between a calm, focused mind and a harried, inattentive self.Anyway it ties in with some of the ideas that I was thinking of after speaking to mc. It fits in with Kelly Lambert's ideas too.
Here is how Frank applies the ideas...it comes down to moving being healthy.
