I believe that the Good Lord gave us a finite number of heartbeats and I'm damned if I'm going to use up mine running up and down a street. -- Neil Armstrong

Maybe he shoulda done the math. Using his logic, if exercising increases you pulse rate from 70 to 140 beats per minute for 30 minutes per day and decreases your pulse rate from 70 to 60 beats per minute the other 23 1/2 hours per day, how much longer would you live after 50 years of this?

  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... ).

    I 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?

      Altheles may have a genetic predisposition to be more healthy. Regular exercise may reduce risk of clotting but it may not have much influence on the upper bound of your lifespan. 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 ).

        Yeah, I've been grading exams the last two days. It's hard to be diplomatic after a while.
