I thought sometimes means that adult children sometimes live at home.

I think for the most part the older guys are trying to keep all their options open. I dated a guy once that was 68, and had a 15 and twin 13 year old girls. She wanted kids, he wanted her. The irony was he never saved for retirement, lived the high life, and when he had to retire ended up renting a room from his former mother in law, the grandmother of his daughters, and she is younger than he is. One date with him was enough, I don't want school age kids in my life, unless they are my grandchildren. His life just had too much drama and baggage for me to deal with.

I ended that at 24.
