A human heart beats about 70 times per minute. If an average human being lives to the age of 80 how many times does the average heart beat in a lifetime?

I come up with 8,064,000. Is that right?

wow... that looks way under

70 /min

70 x 60 = beats per hour

70 x 60 x 24 = beats per day

70 x 60 x 24 x365 = beats per year

I'll let you figure beats in 80 years
