Christopher McDougall: Are we born to run? | Video on TED.com
This video searches the mysteries of the Mexican Indians who are great runners with a remarkable ability to remain extremely healthy. It also delves into the huge heart of a distance runners.
I also explains how women are not great at shorter distance races but that women excel in long distance running. As of date, the fastest women Paul Ratcliffe is only 10 minutes off of the mens world record of the marathon distance.
It also explains that as we age, we can be just as competitive at age 60 as we were as a young adult. It explains how we have a huge advantage because we are able to sweat. It is a very interesting video.
