Wow, I don't remember anyone claiming that Biden wasn't old, but that was never the point, was it? Nope, you claimed that it was obvious that the man was suffering from "dementia" and after requesting that you provide proof, you claimed that you did not have access to his medical records. I then provided them for you. Your snide comment about his stuttering problem does not at all dispute actual facts, which is that he actually does not suffer from "dementia"...If you wanna have a discussion, please try to keep things in their proper context.
First, I'd like to know why you say he's an "heartless bastard", because he's neither? Second, how many times have you had to endured the same itinerary and in so many different time zones as Biden has in the last few days? It's surely taxing on the mind and body, even for a young man. Should Joe run again? No, but for reasons known only to yourself, you are somehow regaling in someone else's misfortune...kudos.
