Too comment is the most accurate. But to help you understand why everything is so fast realize this: your body is only a couple feet long; your blood is traveling around 3mph.
Your heart is one of the hardest working muscles in your body for a reason. Your blood travels fast and your lymph travels nearly as fast(?)
