One of my cousins, and my best friend's daughter, have Down’s Syndrome. At one time this might have resulted in early death; in the past, few Down’s patients lived past early adulthood. Today, many survive to live reasonably happy, productive lives, with proper support and assistance.
And BTW, the picture posted with the article shows a young man, an adolescent boy really, who does not have any classic Down’s features.
Correct. Whatever psychological issues the young man may have, he does not have Down Syndrome.
