The Laws of Physics is the number one cause of aging. This means that it doesn’t matter if the subject is biologically alive or not, everything is subject to aging caused mainly by the damage that occurs through the normal operation of a subject through a natural course of time. As Aubrey de Grey would put it, if we can fix a car or an air plane when its parts are damaged and defective, we can do so too with the human body. But the human is different from a machine so defeating biological aging, while it is possible with today’s technology and as it progresses, will not happen overnight.
