Denis Vashurin from Russia became widely known after sharing his story online, because although he looks like a 14-year-old boy, he is actually 37. His youthful appearance is the result of a rare genetic condition that slowed his physical development when he reached his early teens. Denis says he was an average-looking child until around the age of 12 or 13, when his body simply stopped aging at a normal pace. Doctors have never given him a clear diagnosis, but they confirmed that aside from his slowed physical growth, he is completely healthy. Growing up was not easy for him. People often assumed he was much younger than he truly was, which led to misunderstandings in school and later in adult life. Denis says he still gets questioned when showing his ID, and strangers sometimes doubt that he is an adult because of his small frame and youthful face. Despite this, he continues to live a regular adult life—he works, drives, pays bills, and maintains long-term relationships like anyone his age.
