The Effect of Relativity Theory on Marathon Runners :: physics sport sports running

Sometimes people say, Running is good for your health, and you arouse live longer. Is it true? Isnt there another reason? Is health the solely cause of longevity? I wondered if the effect of relativity is one of the causes. In 1905, the great physicist, Albert Einstein, put forward a new theory called The special(a) Theory of Relativity. It is very simple and it says only these two principles 1. The laws of natural philosophy ar the same in all inertial system. 2. There is a speed limit, and it is the speed of light. Suppose two inertial systems, one of which, S, is the confront system and another, S, is moving at the velocity v to S. In in a higher place pictures, red and blue represent S and S, white balls moving are light, green boards are mirrors. Since the speed of light is constant, (ct)2 = (vt)2 + L2 (1)
