7 secrets hidden in your body

　　Body posture affects memory

　　Don't remember your wedding anniversary? Ask your husband to try kneeling down on one knee, and clear memories will emerge in his mind. Likewise, smells or sounds can evoke memories of distant childhood fun. The connection can be obvious (a bicycle bell that reminds you of your old newspaper route) or miraculous. A recent study helps shed some light on this phenomenon, with an article in Cognition stating that recalling past events is faster and better by assuming the same body position as when the event occurred.

　　your skin There are four colors

　　All skin, undyed, will appear milky white. The skin's superficial blood vessels add a hint of blush to it. Yellow pigment gives the skin a light yellow color. Finally, dark brown melanin, produced to protect against ultraviolet radiation, appears black in large amounts. The combination of these four colors in different proportions creates the different skin colors of all living beings on the earth.

　　The brain takes over the territory of the mouth

　　Evolution is not perfect. Otherwise, we might end up with a pair of wings instead of wisdom teeth. Sometimes a species grows useless organs simply because they don't cause much harm. But wisdom teeth aren't always a source of income for dentists. Long ago, they were very useful third molars for chewing meat. But because the increase in brain volume has affected the structure of the jawbone, we have been left with such a burden.
