Vitamin S

A one time banker and centenarian(100 years old) arises at 4:30 am, cycles to the beach, swims for half an hour, runs for half an hour, does yoga, and then meets other Okinawan seniors to stand in a circle and laugh!  When asked why he stated it is vitamin S, “you smile in the morning and it fortifies you all day long.”  The Blue Zones, Dan Buettner.
