Neil Armstrong could be right. He may be referring to Kleiber's law ( http://en.wikipedia.org/wiki/Kleiber%27s_law http://en.wikipedia.org/wiki/Kleiber%27s_law ) and the Metabolic theory of ecology ( http://en.wikipedia.org/wiki/Metabolic_theory_of_ecology http://en.wikipedia.org/wiki/Metabolic_theory_of_ecology ). Apparently, "for most organisms, the average # of heartbeats in a lifetime is equivalent. Elephant ~ 30 beats/min. Shrew ~ 1,000 beats/min" ( http://members.cruzio.com/~zdino/psychology/ecology.htm http://members.cruzio.com/~zdino/psychology/ecology.htm ). "The size of these hearts differs enormously, but over the course of each species’ lifetime, they appear to beat the same number of times - approximately 1 billion" ( http://www.wellcomecollection.org/exhibitionsandevents/pastexhibitionsandevents/heart/WTD027771.htm http://www.wellcomecollection.org/exhibitionsandevents/paste... ).
- Agathos 18y agoI think edw519's point flew past you. Here it comes again: A resting athlete's heart rate is lower than a resting couch potato's heart rate. What does that mean in the context of what you just posted?

A search for '"twin study" resting heart rate' found that a few genes significantly affect resting heart rate ( http://www.biomedcentral.com/1471-2350/7/17 http://www.biomedcentral.com/1471-2350/7/17 ) and that environment significantly affects active heart rate ( http://circ.ahajournals.org/cgi/content/full/94/8/1864 http://circ.ahajournals.org/cgi/content/full/94/8/1864 ).

- Agathos 18y agoYeah, I've been grading exams the last two days. It's hard to be diplomatic after a while.
