My dad was 20 years older than my mom and I was 20 years younger than her. My dad was 40 when I was born, obviously.
I'm older than the wife by several years. I was 50 when my only child (a son) was born.
But even better than that is this true story.
I went to see my dentist. He was getting old and I had been seeing him since I was a kid. He knew everybody in the county and their family history. So I said to him, "I guess you heard I've gotten married again and had a child." He goes, "Yes I did and , congradulations." Then I said, "Kindda foolish a man my age having kids this late in life ain't it." He says, "Oh, I don't know about that. My dad was 64 when I was born and there were 2 more after me." I didn't feel near as bad about my age and parenthood after that....
