She'd been told that childbirth was going to be painful. But as the hours wore on, nothing bothered her — even without an epidural.
"I could feel that my body was changing, but it didn't hurt me," recalled the woman, Jo Cameron, who is now 71. She likened it to "a tickle." Later, she would tell prospective mothers, "Don't worry, it's not as bad as people say it is."
It was only recently — more than four decades later — that she learned her friends were not exaggerating.
Rather, there was something different about the way her body experienced pain: For the most part, it didn't.
Scientists believe they now understand why. In a paper published Thursday in The British Journal of Anaesthesia, researchers attributed Ms. Cameron's virtually pain-free life to a mutation in a previously unidentified gene. The hope, they say, is that the finding could eventually contribute to the development of a novel pain treatment. They believe this mutation may also be connected to why Ms. Cameron has felt little anxiety or fear throughout her life and why her body heals quickly.
