Do you feel like a Ferret?

  A recent study conducted at the University of Arizona in Tucson delved into the question of whether humans and other species were driven to run because of their evolutionary history. After all, primeval man had to run after his dinner on a daily basis as do the animals in the wild.  Moreover, did we develop a reward response to this aerobic activity in order to guarantee our continued existence? I definitely get the runner’s high after a good-long-run, so much so that I crave the next run even though I do not actually enjoy the act of running while engaged in it. So when neuroscientist conducted this experiment they used test subjects who were runners and non-runners.  When comparing humans to Ferrets for instance, the human test subjects had increased levels of endocannabinoids, the chemical that alters one’s mood. The Ferrets who represented the non-runners--as a rule ferrets don’t run much--did not show any neurobiological pleasure from running.  So now the question which remains unanswered is why do most humans hate running if in fact this is part of our evolutionary drive?  Or more fitting for this discussion site is whether you ladies get the pole high?http://well.blogs.nytimes.com/2012/04/25/the-evolution-of-the-runners-high/
