Some Facts, About The Human Body _ Part One

1.       Tongue: Every person has a unique tongue print, just like fingerprints. The tongue is a unique organ in that it can be stuck out of the 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.

2.       Skin: 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.

3.       Orgasm: Having orgasms prevent men from prostate cancer. Two large studies, reported in 2003 and 2004, found that middle-aged men who had (or at least remember having) at least four orgasms a week throughout their 20s, 30s and 40s had a reduced risk of prostate cancer by as much as one-third. Some researchers speculate that ejaculations may clear the prostate of carcinogens.

4.       Foot: The foot is home to the body's thickest area of skin. The skin on the palms and the soles of the feet are 4 mm thick and the thickest skin in the body, the heel portions of the feet being the thickest portions. It's also got the most sweat glands than in any other area.

5.       Appendix: The Appendix isn't as useless as you think. Long denigrated as vestigial or useless, the appendix actually has a reason to be – as a “safe house” for the beneficial bacteria living in the human gut. The beneficial bacteria in the appendix that aid digestion can ride out a bout of diarrhea that completely evacuates the intestines and emerge afterwards to repopulate the gut.

6.       Height: The body is taller in the morning than in the evening. The body is taller in the morning than in the evening. You might want to schedule that basketball game for first thing in the morning. That's because our bodies are on average about half an inch taller in the morning, thanks to excess fluid between our discs, which is replenished while we sleep. As the day goes on, and our bodies undergo the strain of standing, the discs get compressed and the fluid seeps out, so the body loses that small bit of extra height.
