Recently, NASA scientists have noticed that astronauts exposed for extended periods to absence of gravity might suffer from dyslexia probably due to a degeneration of the cerebellum caused by the alteration of the motor activity in space (Meikle, 2001).

Therefore physical movement appears to be fundamental even for the development of a complex ability such as speech. But in spite of the uniqueness of the human race, our DNA is for 99% identical to the one of chimpanzees.

Man biologically designed to move, hunt, run and fight has been able to evolve transforming reality to such an extent that he could eliminate the problems he was programmed to overcome.

Therefore hunting, fasting and hard physical work have disappeared from the life of most of us in developed countries leaving largely unused our biological system.

Especially the musculo-skeletal system that constitutes the largest part of our body mass because so essential in the biological program initially foreseen for the human race.
