Do you see anything selfish about having a child later in life?
There is a difference between the guy who is 55 and his wife is 44 and she has a late pregnancy, and the guy who at age 65 says: "I've spent my whole life partying and now I have no heir, no legacy! I need a cocktail waitress and prenup, stat!"
There is also the guy who legitimately does not meet a compatible person until he is older.
My mom was 42, my dad 53 when I was born. My siblings were 20, 18, and 13. I was not a planned baby and I was blessed to have two wonderful parents who decided my life was more important than the sacrifices they would have to make to raise me. They did everything to make my life happy and vibrant. My dad died when I was 22 and my mom lived to 83, I was her caretaker and can not tell you how many times she called me her blessing.
