Lucho is Right! We are Made to Run
And Discover magazine says so here. The other day I was sitting in a chiropractor's office an hour outside of town. I'd heard this guy was special so I decided to see what it was like to be in the presence of a "true healer." But that is a story for another post.
Needless to say while in a waiting room decorated with a tomahawk, some antlers and a four foot tall wood carving of a bear begging for food, and underneath a mountain of hunting and fishing magazines, I found an old Discover magazine. My synchronicity must have been working overtime because it literally fell open to an article entitled, Born to Run. And since I've been doing this run every day experiment, my interest was peaked.
Basically the article explains that humans are actually more efficient runners than horses, or gazelles, or even cheetahs. While all of these animals are faster than we are, humans have evolved to be able to run for longer periods of time at slower speeds. We can run for days apparently. This made us good at running our food down even though it might have been faster than we were. Quite a bit of scientific evidence goes into this but even things like our spines come into play allowing our heads to counter balance the movement of our arms. And our skin is one huge cooling system supplementing our cardiovascular systems ability to shunt heat from our core to our skin via the blood while our sweat and air flow carries the heat away from our bodies. It is a really good article. Be sure to check it out. Then stop by Lucho's blog because Discover is just saying what he's been saying all along.
