About how many times does the heart beat a minute on average throughout a person's lifetime?

Explanation:
Think of the heart as running at a fairly steady pace over a person’s life. A commonly used rough average for an adult’s resting heart rate is about seventy beats per minute. If you take that pace and multiply by the minutes in a day, then by roughly seventy years, you get around 2.5 billion heartbeats in a lifetime. That makes seventy beats per minute the best match to the widely cited lifetime total. The other options reflect slightly different resting-rate assumptions, but they don’t align as closely with the usual lifetime estimate.
