It might seem unusual that not exercising could lead to depression, long thought a disorder of personality.

In depressed patients, whose levels of catecholamines are abnormally low, healthy levels can be restored by giving antidepressant drugs, BUT the NATURAL solution to accomplish this is through regular exercise.
