The Romans knew the secret thousands of years ago, Butler says.
Question: What is the relationship between mind and body?
Robert Butler: Well, the Romans knew 2000 years ago, sound mind is a sound body. So, if you have good physical activity, you are apt to have good mental activity and in fact that is one of the reasons I have a walking group. So that each Saturday and Sunday morning we walk together, which helps us to walk 5 or 6 miles and to keep us in good shape, mentally and physically. Recorded on: Mar 17 2008
