Product Description

Imagine an observer sitting beside an oval race track, with a motorcycle rider traveling close to the speed of light for several years around the track. The sitting observer will age faster and time for the motorcyclist will pass relatively slower. This follow up formula to Einstein’s mass-energy equivalence is proof positive that motorcycling gives you more energy and enjoyment out of life. Riding faster ages you slower than non riders too! Ride fast and take chances. 100% cotton. White. M-XX.
