The body maintains itself. For as long as the body maintains itself (internal maintenance systems) that is the length of life. There are no pharmaceuticals or magic food that you can take or can help.

Confronted with this fact and with the complexity of the human body, the entire medical system including pharma is goes by the way of being a scam. Up to 90% percent, for instance.

People are ignorant, and they damage themselves in ways they do not know and beyond the maintenance system's ability to keep up. Age is different in this case.
