Progeria when something young grows old in a short period of time.
Josiah suffers from progeria, a genetic disease that causes accelerated aging in children. Its name, of Greek origin, means "prematurely old." Incurable, progeria is among the rarest diseases on Earth and affects roughly one in 4 million.
Dr. Colleen Walsh, who treats Josiah, said it was hard to tell how old his body is.
"About one year was equal to about 10 years," Walsh said. "Josiah's looking at being between an average 60- to 70-year-old."
