Every day our bodies are dying, or rather, our millions of cells are dying. Fortunately they do not all die at once, and there is always another cell to take its place. What if people could stop their cells from dying? Wouldn’t that be the same as eternal life? Well that is not possible, so the best people can do is delay the cellular inevitable. To do so merely entails exercise, an activity that people should be doing anyway. An Italian team of scientists at the University of Rome put their collective skills together to prove this hypothesis.
