`When you first meet 4-year-old Roberto Salazar, you can’t help but notice his unwavering smile and constant laughter. By all accounts, he’s a very happy boy.
It is only when he rams his head violently into walls or plays a little too roughly with a schoolmate, all the while smiling, that you are reminded that he suffers from an incredibly rare genetic disorder.
Roberto is one of 17 people in the United States with “congenital insensitivity to pain with anhidrosis,” referred to as CIPA by the few people who know about it.’
