Which part of the human body is most sensitive to touch?
Touch is one of the basic feelings of the skin. Contacts are scattered on the skin surface, with different sizes, some of which can reach 0.5 mm in diameter. Its distribution is also irregular, generally the abdomen is the most, followed by the head, calf and back are the least. Therefore, the fingertips are the most sensitive to touch, and the calves and back are the most dull. Touching your finger belly with thread will have obvious touch, while touching your calf will be completely unconscious. This is why you can know whether you need a card by touching it with your fingers without looking at the cards when playing mahjong, but touching your back skin with two blunt needles 0.5cm apart is mistaken for an object.
