Black people absorb all the light, and their skin is healthy … short-lived, while white people reflect all the light, and their skin is easy to get sick and live longer … how to explain this phenomenon?
Black skin does absorb more ultraviolet rays; But black skin has a great advantage that it can better protect the blood vessels and nervous system under the skin, so it is not contradictory; Moreover, the black palm and sole have large pores and many sweat glands, which are different from our structure. Darkmouth is big, and it can dissipate heat well. Hair curls, and the air in the hair can also be insulated; Black people have the least body fat, so they are afraid of cold and heat; And there are basically no black swimmers, because they are all muscles, no fat, no buoyancy, swimming is very tired, so you see a lot of black boxers. Why? Because it's all muscle and explosive power, you can KO you with one punch.
White people have the highest body fat content, so they are very hardy. White people are hairy and big, all for better warmth. You see, all the swimmers in the world are white. Why? Because of high body fat and high buoyancy, fat can be converted into heat, so white people have good endurance, white skin and reflective skin, and can survive in cold places, and it is not easy to lose fat.
