BUILT TO CONSERVE ENERGY

Our upright stance is very energy efficient, for it demands little muscle action to sustain the vertical alignment of our body. In fact, we ‘use only 7% more energy standing than when lying down,’ says neuroscience researcher John R. Skoyles. He adds that a dog uses about 70 percent more energy when standing (on all fours) than when lying down.

Appreciate Your Special Gifts

THE human body is outstandingly versatile. No animal has the sheer range of abilities that we humans do. One reason for our versatility is our upright stance, which not only expands our area of vision but also frees our arms and hands for any number of tasks. Imagine how our activities would be curtailed if we had to walk on all fours!
