On the face of it, it's pretty absurd. If a human has an average heart

Don't think so.
And it is inverted within the species -- small dogs live longer than
large dogs (large dogs having heart rates of 60-100 bps), yet have
higher heart rates (100-140 bps).

Anyway, how do you pin down this invariant unless you know the cause of
death was heart failure?
