The average heart rate at rest is about 70 beats per minute.

That's 4200 beats an hour

100,800 beats a day

36,792,000 a year

If a person lives until they are 80, then their heart will beat about 2,943,360,000 times!

Please note that this is based on a persons resting heart rate and does not take into account the increase in heart rate when we exercise.

Also, our heart beats a lot faster when we are children, therefore the actual figure is probably a lot higher!
