Did you kn ow that the human being can outrun for distance any animal on the planet?  We can outrun dogs! There is no creature on this planet that is able to sustain itself in a running race with a person. Our legs are disporportionally long, compared to most things, except maybe an ostrich, but we have a much more advanced cooling mechanism, sweat glands over almost our entire body. The human machine is the most technically advanced living being that we know of in the universe. I can do 11 pullups!
