A New Jersey woman has achieved something that's not easy to do.

FOX's Dave Anthony reports:

How old is Adele Dunlap? She's so old, She tops the list. The oldest person in America.

Dunlap's 113 and became number one and the tenth oldest in the world when Goldie Michelson died in Massachusetts, according to the Gerontology Research Group.

Dunlap lives at a care center in Pittstown, New Jersey. Her son, who's 86, has no good explanation for her longevity that mom never went out jogging or anything like that, smoked for years and has pretty much eaten anything she wanted.

Dunlap will turn 114 in December, though fibs, if you ask her age, insisting she's a lot younger, only 102.
