Anatomy FunFact II
Knee or back pain? Here's a precis from my anatomy book:
Gorillas, chimps, and gibbons sleep on their sides, using only arms & hands as pillows. Head down, mouth shut, bottom ear unobstructed. The stretching movements that accompany respiration in this position repeatedly realign joints between the vertebrae - impossible if a pillow is used.
Pillow use also keeps the feet dorsiflexed, which rotates the knees so that the angle between the patellar tendon and quad is odd, leading to eventual pain.
Another bonus! WIthout a pillow, if a male brings his knee up to the elbow, quite a comfortable position, the penis extends along the flexed leg, protecting it in the curve of the body. Members of African tribes taught western researchers to sleep in this position.
