Causes of Aging

June 16, 2016
Cantor believes that similar to how an automobile breaks down with use over time, the human body is remarkably similar. However, instead of mechanical components we have biological ones. As we age, our body is under constant seige from the environment. From carcinogens in the food we eat, to the DNA adducts induced by UV light from the sun. Even if we lived in a bubble, void from all environmentally induced DNA and epigenetic damage, whenever a cell divides to replace old cells (i.e. skin sloughing off), the copy is never as good as the original and mutations are inevitably introduced during the process of cellular division.
