Dr. Denham Harmon, M.D., Ph.D., first proposed a theory of aging as the indiscriminate chemical re-activity of free radicals possibly leading to random biological damage.
His idea has had much experimental success, and it is now considered a major theory of aging. Dr. Harmon's theory implies that antioxidants such as vitamin C and vitamin E, which prevent free radicals from oxidizing (removing electrons from) sensitive biological molecules, will slow the aging process.
