...metabolism sets the pace for myriad biological processes. An animal with a high metabolic rate processes energy quickly, so it can pump its heart quickly, grow quickly, and reach maturity quickly. Unfortunately, that animal also ages and dies quickly....There is a universal biological clock..."but it ticks in units of energy, not units of time."
