Aging can affect the physical and psychological well-being of a person. The physical signs of aging which include increased body especially around the waist, decrease muscle mass and wrinkled skin contribute to the psychological effects of aging.
The psychological effects include reduced sense of well-being, low energy and vitality, mood swings and depression. The thoughts of aging itself can bother a lot of people. This explains why for so many years, even during ancient times, people have been looking for the fountain of youth.
The scientific community seems to have unraveled the fountain of youth when they discovered the relationship between hormones and aging. Essentially, their researches pointed to one important hormone, the human growth hormone (HGH).
