You may not have heard this, but this all got started when scientists started calculating the number of lifetime heartbeats of various creatures, from hummingbirds to elephants. It turns out that all species, if they live out their natural lifespan, get about a billion heartbeats.
We have a slower heart rate than mice and we outlive them. But what about within a given species? Do people with slower heart rates outlive their contemporaries whose hearts beat faster? The answer appears to be yes.
