A remarkable 17-year-old young man died in New England a few weeks ago. His name was Sam Berns, and he had a rare disorder called progeria, which results from an untreatable genetic mutation that causes aging of all the body’s cells. Sam was diagnosed shortly after birth with this affliction, which occurs in one in 8 million newborns. His parents, both physicians, formed a foundation to conduct research on the condition. Throughout his short life, they also wisely advised Sam to choose activities that would enrich his life most fully.
