@nandric , how many people have you watched age over a lifetime? Not very many obviously. As JFK relates, "Old age is a train wreck." Nobody, and I mean nobody has the manual dexterity at age 80 that they had at age 24. Some are better than others. "Going Strong" for most 80 year olds is still breathing. Yes, I know some 80 year olds that are still running 1/2 marathons and I had one patient who at 84 could still dead lift 480 lb but these are the rare exceptions. The 84 year old had stopped working on his own cars because he was having difficulty with his eye site.
Old age is something you have to cover up with humor and the sensibility to retreat from activities that have become to dangerous either physically or legally whilst giving up as little ground along the way as possible. You can't think about it, too depressing, just as bad is painting it as something it is not.
One thing I can say about you nandric is your mental capabilities are still going strong. Keep eating those jellyfish pills:)
