Physiologically speaking, Brooke Greenberg is an infant with the mind of toddler. Only thing is that she turned 16 just this Janary. It’s hard to estimate the parents opinion, especially as I wasn’t able to find almost any constructive data.
“Many of the best-known names in medicine, in their experience … had not seen anyone who matched up to Brooke,” Pakula said. “She is always a surprise.”
She is not aging, but it seems that her body is developing as independent parts out of sync. If you were to look at photos, she is unchanged, and there’s no indication that she would be in fact getting any older, and as far as everybody knows, if this continues on, she has no reason to die. She also has a sister, but she’s perfectly normal, so there aren’t any hints here to help solve this mystery.
“Why doesn’t she age?” Howard Greenberg, 52, asked of his daughter. “Is she the fountain of youth?”
