The human body is in constant motion. Your blood flows, your lungs inflate, you pass gas, and your body hums along at high sppeds. But just how fast do these functions move? Some of them travel faster than a speeding car, while others move about as fast you can peddle a bike.
Of course, each body is different. The velocity of body functions varies depending on how healthy you are, if you're engaged in sexual activity or other strenuous acts, as well as environmental conditions. The mph of your bodily functions may not seem NASCAR fast but they will surprise you.
