Romantic melodies and rhythm combined with anatomical lyrics and a dollop of humor!
Recent studies are finding that every mammalian species has the same number of heartbeats per lifetime after which death occurs. That's why elephants and whales with slower heartbeats live longer while shrews live much shorter. The kicker is humans and our use of medical science to keep us going longer than the rest of mammals. (This includes our domesticated pets for which we also use medicine to keep 'em tickin').
