No pain, no gain.
Congenital analgesia is an incredibly rare genetic disorder that prevents a person from feeling physical pain. It's estimated that fewer than one out of every million people are born with congenital analgesia and only around 20 cases have been documented in scientific literature.
The homozygous mutations of the PRDM12 gene, while sounding beneficial, can be extremely dangerous. People with this insensitivity miss out on important pain warnings, including cuts, broken bones, or extreme temperatures. Our pain sensors are essential for survival—just imagine the physical danger of unknowingly showering in boiling water or being bitten by a venomous snake.
