The average human heart beats 3.5x107 the
average human lifespan.
To find out how many times the average human heart beats in a lifetime, we need to consider the average human lifespan and the average heart rate.
1. Determine the average heart rate: According to medical literature, the average resting heart rate for adults is around 60-100 beats per minute (bpm). Let's assume an average heart rate of 70 bpm.
2. Calculate the number of heartbeats per hour: Multiply the heart rate (70 bpm) by 60 minutes to get the number of heartbeats in an hour.
70 bpm x 60 minutes = 4,200 beats per hour.
3. Calculate the number of heartbeats per day: Multiply the number of heartbeats per hour (4,200) by 24 hours to get the number of heartbeats in a day.
4,200 beats per hour x 24 hours = 100,800 beats per day.
4. Calculate the number of heartbeats in a year: Multiply the number of heartbeats per day (100,800) by 365 days to get the number of heartbeats in a year.
100,800 beats per day x 365 days = 36,792,000 beats per year.
5. Calculate the number of heartbeats in a lifetime: Multiply the number of heartbeats in a year (36,792,000) by the average human lifespan. According to World Bank data, the global average life expectancy is approximately 72 years.
36,792,000 beats per year x 72 years = 2,650,464,000 beats in a lifetime.
Therefore, the average human heart beats approximately 2,650,464,000 times in a lifetime (rounded to the nearest million).
