Abstract: Collagen is the commonest protein in mammalian. Its function is thought to be only of structural support. New US
patents claimed that it has another very vital role in the human body which is piezoelectricity. Most of the chronic diseases in the
elderly are caused by the disturbance of this newly discovered function. The exact site of disturbance is defined as the site (Y) of
collagen. Profound molecular and biomechanical studies were done at the site (Y) to determine its mechanical disturbance from
the pathological point of view. As collagen is present all over the human body like bone, cartilage, the heart, brain, blood vessels,
skin, even the sclera of the eye, its correction would recover most of the tissues of the human body. This paper discusses the site
(Y) and its effect on piezo-electricity and its glycation. It discusses also all the factors that may affect the site (Y) either damaging
or recovery in the hope of avoidance of all the destructive factors and enhancing the repairing ones. It is believed that this new
method of thinking about the degenerative disease in the elderly could be treated perfectly, more physiological, and also at the
root level. This is much better than treating each disease as a separate entity. Lastly and for most, this group of degenerative
diseases has a great impact on the health care system and hospital resources of every nation. Thus, the recovery of these patients
would save a huge amount of money spent in the health care system for these chronic and almost long-lived diseases.
