"She graduated from college in 1969. I think she was born in 1947."
The nndb database (accuracy unknown to me) lists her birthdate as September 7, 1950, and year of HS graduation as 1968. It appears, though, she was on the six-year plan in college, graduating from Farleigh-Dickinson in 1974.
As for whether she has aged well, she seems to have a look appropriate to her age (55 - same as I am) but maybe that's why I have a much younger wife!
