He is about that age and I have thought this for a while now and posted so a few times. As you stated you probably doubt he is aware he is getting old.....I can assure you his wife is letting him know each and everyday. You don't have to be a genius to know that time waits for no one. Just get up every morning and you have joint pain that reminds you of this. You may see a buyout sooner than you think. There's that word "sooner" again. LOL
