Many times in our lives, we will dance with pain, and in order to avoid pain, humans have invented various anesthetic needles and painkillers. There are a very small number of people in the world who do not know what pain is all their lives, but they are not happy. In Minnesota, a girl named Gobby loves to nibble her fingers, but if no one stops her from nibbling, she will nibble her fingers until the flesh is blurred. A little boy in India, less than 15 minutes after his parents left him, ate his fingers alive. These children are suffering from an extremely rare disease - painlessness, ta are born without the ability to perceive pain, and because of the lack of pain, it also means that they are vulnerable to more injuries in life. Although the rare genes of painless patients have brought some progress to medicine, for painless patients themselves, the suffering of TA is still endless.
