Sure, why not. I mean, if men can be fathers at 60, then so should women.
I'm kinda surprised this actually happened, considering how old her body is. I've never heard of a woman actually being able to get pregnant at the age of 60.
Too bad that the child will most likely not have so much time with her as he or she probably could otherwise... I mean, the woman is getting old already and her child might see her die sooner than he/she might like.
