well 72 bpm is kinda low, its when people do not have any physical activity.... it also depends on your body. if u are a skinny geek like i am you have a small heart (coz u have a small chest) and it needs to pump faster to irrigate your brain.Originally Posted by teknorich
and about the 220 bpm thing... well you can reach this when you run to ctach your bus ... its not th music that is responsible, its simply becasue you dance
