M.L.
When I made my debut, my father was 42 and my mother was approaching 40. It never worried me or bothered me. Once in a while somebody would think I was with my grandparents, but we all laughed at that. I sometimes worried about them dying, but it wasn't because they were older - it was because they were my folks.
When I graduated from college, my parents were in their 60s, and they retired shortly thereafter. They were always busy and I think they were pretty happy, and the age thing was just not a big deal.
My mother also had older parents - she was the youngest of seven children, and had one brother in college when she was born. So it never bothered her that she had children so late. She and my dad simply married later in life; my father wanted to be able to support his wife and children, and he had to get through the Great Depression before he could do that.
If there was anything negative, it would be that to this day I cannot estimate other people's ages! Some people can say, "Oh, that woman must be in her forties," because of the way she looks or behaves. I have never been able to guess at all - probably because my parents were almost a generation older than my friends' parents but their demeanor never showed it (their hair did). But that's not a bad problem to have.
