Perhaps all our troubles - all the violence, obesity, illness, depression, and greed we can't overcome - began when we stopped living as Running People. Deny your nature, and it will erupt in some other, uglier way.

"If you can run six miles on a summer day then you, my friend, are a lethal weapon in the animal kingdom. We can dump heat on the run, but animals can't pant while they gallop."

Christopher McDougall

"Way before we were scratching pictures on caves or beating rhythms on hollow trees we were perfecting the art of combining our breath and mind and muscles into fluid self-propulsion over wild terrain."

Christopher McDougall
