Caulfield: These scientists say every animal gets a billion and a half heartbeats. You use them up, you're done. Lights out. Room temperature. Meaning animals with slower hearts live longer. Frazz: Cool! Caulfield: No, not cool! This has serious ramifications for you, mister exercise! Frazz: What are you talking about? Caulfield: You redline your heart on a daily basis! Frazz: Which is why my heart rate is super slow the rest of the time. Caulfield: Oh. Also, smooching Miss Plainwell has got to rev it up and leave it there. Frazz: That's a quality-of-life choice.
Except that if an average human heart rate is 70 bpm, and an reasonable human lifespan is 70 years, that’s about two and a half billion heartbeats per lifetime.
