Frequently asked
How many times does the heart beat in a lifetime?
About 2.5 to 3 billion, depending on resting rate. It varies less between people than you might expect, because a lower rate usually comes with a longer life.
Does exercise use up heartbeats?
No. Exercise raises the rate briefly and lowers the resting rate permanently, so trained people generally accumulate fewer beats per day, not more.
