Doug, I agree with you absolutely. People can enjoy their freedom for a long time, how they want. They can travel, buy houses, expensive cars, go out to expensive restourants, have many different partners etc (it is a big topic for imagination). it is ok, people can enjoy it, but what is next? I am not going to judge. But, finally what they get? For what they buy all those things? In my opinion, it is unuseful life. We live for our children, for their future, for give them everything we know about the life.
I have a friend, he is an old man, an American. And he never was married, doesn't have children and lives alone. Really intelligent well-educated and friendly man. He could be happy for now, but he is not. He had an own bussiness and had a wonderful life in the past, enjoyed everythong, but for now he is poor and lonely. What is the reason? That is right, for now no one have an interest for him. Do you understand what I mean?
So, you, Doug, is very lucky that you have the son. I think you might find the right woman for you and make her and her child\children happy. I am not agree with Tomazzo that you can't become a father again (I mean to have a baby) why not, if you find a woman who can and wants do it? But you have to understand that your age doesn't let you to care about a baby, to give him an education, to grow up... In my opinion it is better to find a woman with teen and give your knowlege to him\her.
About adopted children from Russia is a different topic. Yes, there are many of them in the US and other countries. But I have to admit, then they are not healthy children, the most of them have much problems with mind. And what is better - to adopt children with diseases or marry a woman with educated intelligent children?
