I didn't see any news about Sanders or Trump that similar to Biden. Maybe it's because of hard working of Biden. But, didn't see any news similar at other presidential candidates.
Please dont get me wrong. Being old is not a problem. Old age is felt much more obvious at Biden as i see. And, as a world citizen, i wonder how it will effect the next election. Which persons will go next election? Who will win? Which president at the US will make relationships with world. And, how they will approach to world problems. All in my interest zone. But, my interest zone is not -interest-ist- zone, only value based.
being old is not a problem for me. its's natural. and, it's cute. (the girl at tweeted-video smiles the cuteness )
events from being old is interesting for me. it can effect next elections.
