Older women actually think this way. I had one that I was interested in years ago say to me "I don't want a cougar baby." That was her nice way of telling me I was too young for and she felt too old to be with me. I guess it makes sense because if the young man wants to father children the older woman is not in a position to satisfy this need because she is at the end of her fertile lifecycle when getting pregnant becomes difficult and risky.
