Aging has to be explained as an Eternal Law which operates and regulates human existence from conception to death.
Age is a fundamental characteristic of most living organisms. The speed of the aging process varies and it is not the same in the entire organism. To establish human birth with a recognizable physical appearance, the cells of the embryo and fetus rapidly multiply and several of them have to simply die after a programmed sequence of cell divisions. Aging is that inevitable process that causes cell death after the lapse of a specified time interval which is programmed. At adulthood (age 20), age acceleration is around 40% and it is 100% in newborns.
