Yes, but I'm also reminded of the little old lady who was still working as a receptionist at age 75 at a former place of employment of mine....the only reason she worked was to financially support her deadbeat daughter and the daughter's children. I think some of the "best" parents are the ones who choose not to have children because--due to a career, for instance--they know they wouldn't be able to devote 110% of their attention to the children if they had them. I can kind of relate because, although I'm an empty nester now, several of my friends who waited until now to have babies are drifting away--all they talk about at parties, is ovulation and morning sickness (I can kind of understand, since having children is such an all-consuming thing, but I occasionally feel left out nonetheless).
If you are an empty nester then you are not too far away from all your friends talking about nothing but who just died, their most recent bowel surgeries and golf scores.
