I just keep looking at the chin, there's a big dent in the new Bidens chin, and the old Biden has a smooth round chin. I get people get facelifts, and maybe the earlobes get sewn back on with the face, but chiseling the bone of the chin until it has a giant dent seems a bit extreme if you're just trying to look younger. Then there's the really pale blue eyes on the old Biden, they weren't a common blue color, I assume contacts couldn't reproduce that considering they're never that light anymore, they're either dark blue or brown looking.
