Imagine living a life where you never really experience physical pain, stress, or anxiety. A 71-year-old woman by the name of Jo Cameron is a very rare case of a genetic mutation that makes her feel no pain. Cameron lived through her childhood breaking her arm and not noticing it until her bone was oddly resetting, eating spicy peppers with ease, and ironing herself with the smell of her own burning skin as the only indication that she was burning. Throughout her life, Cameron never thought anything was different about her. Until she underwent a hand surgery that was supposed to be an excruciating procedure. After this procedure, a consultant, Srivastava, sent her to see pain specialists in London. This research team in London found that there were two mutations that allowed Cameron to experience little to no pain and allowed for a boost in happiness, forgetfulness, and wound healing.
