Who is the oldest survivor of progeria?

As of my knowledge cutoff in September 2021, the oldest known survivor of progeria was Sam Berns. Sam Berns was born on October 23, 1996, and was diagnosed with progeria, a rare genetic disorder characterized by rapid aging in children. Despite his condition, Sam lived a remarkable life and became an advocate for progeria research and awareness. He was the subject of the HBO documentary “Life According to Sam” and gave a widely viewed TED Talk on his experiences. Sadly, Sam Berns passed away on January 10, 2014, at the age of 17. Please note that there may have been developments or changes since my last knowledge update, so it’s a good idea to verify this information with up-to-date sources.
