Well, the old man is fifty. You go through life thinking to yourself "when am I ever going to grow up?" "When will I know enough about life to be an expert?" What I've learned along the way is that you never really grow up, you never become the expert. You give some advice, you answer some questions,but you keep on learning. Some people may think that at fifty "you know it all", but I figure that I'm about half way there........I'll let you know if I was right when I turn one hundred.
