Well, my point is I'm 20 or so years younger and I could have broken a hip. Hell, I took a fall at work today that was doing something I've done a thousand times - I simply tripped, and hit the deck HARD (I am VERY sore right now).
Yes, I get his importance and also his age compared to me. But I also admire the fact that at his age, he's still active enough to even attempt to do what he does. And I guarantee that every single one of us posting on this board, we're still going to believe we can sort of cheat aging to an extent and in our own ways - up until we all reach a point where quite frankly we can't do something we have done our entire lives any more.
It'll happen to me. It'll happen to you. It'll happen to everybody "some day". And yes, it'll also happen to Joe Biden.
That, my friend, is what's called "life" - and none of us are immune.
