20 Year Old Toddler DIES

Brooke Greenberg, the woman who confounded scientists because she never aged, has died at the age of 20, never having developed beyond the physical size of a toddler.

The daughter of Howard and Melanie Greenberg from Reisterstown, Md., Brooke is one of about a dozen children in the world who have what some call syndrome X — a kind of Benjamin Button disorder that prevents them from aging.

Her funeral was Sunday at a synagogue outside Baltimore, family friends confirmed.

“The family is doing as well as can be expected,” Chris Cole, a colleague of Brooke’s father, told ABCNews.com today. “They are going through their traditions this week — the shiva.”
