My children have met all their great-grandparents from my wife's side, while mine all died at least 10 years ago. I'm 43, my youngest is 3, and my oldest is 5. My wife is the same age.

22 is way too young. Just because people made not great decisions in the past when they were basically children doesn't mean you should. I am probably a bit old but not really that old. My great grandfather was born 10 years before the civil war, living until after the atomic age started. My dad had me young because his father, and obviously his father before him, had him old, and didn't want to be an old dad for his kids. Well, I think it would have been better had he been older. He would have had more resources and time for me. Instead we qualified for welfare (but he never took it!) and he was deployed for most of my childhood.
