Make an effort to be humorous throughout the day.
Not only is it beneficial from a physical viewpoint but it diffuses
tension in difficult circumstances and creates an excellent atmosphere
wherever you are.
It was recently reported that menbers of the Tauripan
tribe of South America have a ritual where they awake in the middle of
night to tell each other jokes.
Even tribesmen in the deepest sleep wake
to enjoy the laugh and then return to their state of slumber in seconds.
