Aging
Shaking and trembling of the head and/or limbs, if not caused by Parkinson's disease, sometimes stems from faulty action of the oral sphincter and the lower sphincters. This results in the other sphincters and muscles no longer being under control as well. This is a common problem in older people, and can be a very depressing condition.

Repots from people who have done Ring Muscles exercises suggest that it is possible to restore affected muscles to more of less competent action by means of these easy to performs exercises.
