My money's on Biden. Trump does no exercise. Zero. In fact, this from CNN "After college, after Trump mostly gave up his personal athletic interests, he came to view time spent playing sports as time wasted. Trump believed the human body was like a battery, with a finite amount of energy, which exercise only depleted. So he didn't work out. When he learned that John O'Donnell, one of his top casino executives, was training for an Ironman triathlon, he admonished him, "You are going to die young because of this."" And then there's this "Appearing on “The Dr. Oz Show” on Wednesday, to be aired Thursday, the Republican presidential candidate told Mehmet Oz that he regards hand gestures during campaign events as exercise, according to a statement from the publicist of the show released to the media."
Doesn't Trump play Golf like all the time, isn't that exercise? Anyway they can both live but knock each other out of running for president seems good to me...
