A woman who has never felt pain in her 75 years

There are many people who wish they could sleep for at least one day without pain. They live on painkillers. But there are some people in this world who do not know what pain is. One such person is Jo Cameron from Scotland. Joe is 75 years old

Scientists say a rare genetic mutation has made people like Joe unable to experience pain, fear and anxiety.

Scientists believe that the current results will be useful in the study of pain, wound healing and depression. According to the researchers, this is due to a change in the gene called FAAH-OUT. The researchers also stated that the study will help to find more effective pain relievers.
