'I may drop dead tomorrow' Biden says while promising age isn't a problem

President Joe Biden joined MSNBC's "The Sunday Show with Jonathan Capehart" this weekend to respond to critics who believe he's too old to run for a second presidential term. During the interview, he told naysayers that he could "drop dead tomorrow," and awkwardly grabbed Capehart by the shoulders.

"So let's say Trump doesn't run again. Convince Aunt Gloria that she should stick with you," the television host said, referring to his aunt Gloria Avent-Kindred, who is a frequent guest on his show. "I think it's a legitimate thing to be concerned about anyone's age, including mine – I think that's totally legitimate," Biden said. "But I think the best way to make the judgment is to uh, to, you know, watch me."

At 79, Biden is the oldest person to assume presidential office.

He rambled on, saying that he could "drop dead tomorrow."

"You know, am I slowing up? Am I - don't have the same pace or, you know, and that old joke, you know, um, everybody talks about the, you know, the new 70 is 50 and all that stuff. You know, I, you know, could be - I'm a great respecter of fate. I could get a disease tomorrow. I could, you know, drop dead tomorrow, but I am, in terms of my energy level, in terms of how much I'm able to do."

"I think people should look and say, 'Is it -  could he still have the same... passion for what he's doing?' And if they think I do, and I can do it, then that's fine. If they don't, then they should vote against me - not against me - should encourage me not to go. But that's not how I feel," Biden continued.

Then, the elderly president stepped closer to Capehart, appearing to be less than a foot away from his face as he grasped the journalist's shoulders.

"I can't even say the age I'm gonna be. I can't even get it out of my mouth," Biden said, with his voice lowered to a whisper.
