Who was the oldest progeria person?

As of my last update, the oldest known person with progeria was Sam Berns, who lived to be 17 years old before passing away in 2014. Progeria, a rare genetic disorder characterized by accelerated aging, typically leads to a significantly shortened lifespan, with most individuals not living past their teenage years. Sam became well-known for his positive outlook on life and was featured in a documentary titled "Life According to Sam."
