TIL of a boy in Pakistan that would stab himself with knives to entertain others. Researchers found he carried a rare gene mutation that prevents pain nerves to transmit their signals to the brain. - eviltoast

Feeling no pain is actually terrible as you won’t know when you hurt yourself and you don’t properly learn to avoid dangerous situation. People with this mutation have to rely on others for danger assessment as for example they won’t notice easily that they have open wounds or even broken bones. Tragically this boy died at the age of 13 when jumping/falling off a building; the sources differ but it’s likely that he engaged in risky behavior if he couldn’t feel any pain from falling.

Edit: The original title improperly stated that the boy was from India. Corrected it to Pakistan.
