First, the average heart rate is given as 72 beats per minute.

To find the number of beats in a 30-day month, we multiply the average beats per minute by the number of minutes in a day (24 hours x 60 minutes):

72 beats/minute x 24 hours/day x 30 days = 103,680 beats/month

Next, to find the number of beats in a year, we multiply the beats per month by the number of months in a year (12 months):

103,680 beats/month x 12 months/year = 1,244,160 beats/year

Finally, to find the number of beats in a lifetime, we multiply the beats per year by the number of years (72 years):

1,244,160 beats/year x 72 years = 89,462,720 beats in a lifetime

Therefore, if you live to 72 years of age, your heart would beat approximately 1,244,160 times per year and approximately 89,462,720 times in your lifetime.
