I really enjoyed the show, but like you guys mentioned, he doesn't look too good. Being old enough myself to have been a kid who worshipped Shula during the glory years of the early 1970's, it is sad to see what I remember as a young and healthy guy now in his 80's. But as I said to my wife as we were watching it, that will be all of us some day.
That's why they say live life to its fullest. Because at one point, we will all be worm food. I feel sorry for old people who claim they only had a "few good days and bad days" in their life. I want a lot of good days and a lot of bad days in a very intense life. Then when I lay down for my eternal rest, I can look back and say it was a helluva ride.
