Shows how amazing evolution is at "designing" complex efficient systems. Our hearts beat for 70-100+ years without a charge.

  Don't know about you, but my heart needs a charge every six hours and it goes in hibernation mode every 12 hours. Can I upgrade to yours? :-)

    If your heart stops beating for 12 hours, maybe you need to talk to your doctor.

  Pretty amazing that it was a result of a lucky mutation. I wonder what happened to the millions (billions?) of organisms that couldn't maintain a steady heartbeat?

    They had their lunch eaten by the heartbeaters, and when we were done eating their lunch, we ate them :)

  I'm pretty sure you have to eat every so often for your heart to keep on working...
