A friend of mine when I worked at Boeing advised me to always take the elevator, because one is only allocated so many heartbeats, and he wanted to conserve his.
That line of logic to me was always just absolute wild.
Like, yeah, eventually you will die, so yes, the number of heartbeats you'll have is finite. But it's not like you get some limited allocation and when you consume them all, you're toast.
The reality is the opposite which is counterintuitive to those folks: The more heartbeats you use, the more you get. At least, that's true if your extra heartbeat usage is from aerobic exercise, not just being unhealthy and having a high resting heart rate.
