He's aging faster than Obama or Dubya. Biden was always decrepit so it made it harder to tell. Closest one to Trump might have been GW or Reagan. Remember how Dubya looked at the end of his terms? Get a picture of that up. By the end of his two terms, he was a completely different man from the one who was elected. White hair, white beard, walking with a cane, and he had this thing where he squinted like an old prospector who hadn't seen sunlight in 20 years. The office took a toll that's for sure. You can see Reagan really starting to show it at the end as well.But Trump? Man is looking even worse. Even when he was senile Reagan had this sort of jovial twinkle in his eye that seems to be long gone from Trump. Trump has the same vacant stare but with a layer of paranoia and rage under it.
