Taking a nap at work is good for your boss
A 20-minute nap can improve your overall alertness, boost your mood, and increase productivity. William Anthony, co-author of The Art of Napping at Work (Larson Publications, 1999), says the post-nap boost can last for several hours. In addition, your heart may reap benefits from napping. In a six-year study of Greek adults, researchers found that that men who took naps at least three times a week had a 37 percent lower risk of heart-related death.
Ejaculation may cause men to sneeze
Some men experience pain, headaches, or sneezing as a result of ejaculation. The increased activity in the nervous system during orgasm may be the culprit in triggering headaches. A possible explanation for the sneezing is that in the brain, the center for orgasms is close to the centers for yawning and sneezing.
Every person has a unique tongue print
Just like fingerprints. The tongue is a unique organ in that it can be stuck out of mouth for inspection, and yet it is otherwise well protected in the mouth and is difficult to forge. The tongue also presents both geometric shape information and physiological texture information which are potentially useful in identity verification applications.
White skin has evolved over time
It seems we were all black ones (consistent with evolutionary fact of first humans in Africa). White skin was a result of humans moving away from the equator. Also all skin, without coloring, would appear creamy white. Near-surface blood vessels add a blush of red. A yellow pigment also tints the canvas. Lastly, sepia-toned melanin, created in response to ultraviolet rays, appears black in large amounts. These four hues mix in different proportions to create the skin colors of all the peoples of Earth.
