Are you worried that Old Joe could die with a heart attack in his Oval Office and..?

Joe appears real healthy, he replaced a guy who looked like a heart attack in progress.

For those too dumb to read life expectancy (actuarial) tables, the average 78 year old American male can look forward to 9.37 more years.  Biden is healthier than most, and will get the best health care in the world so more for him.  BTW, the "red button" only ordered a diet coke, and Biden had that removed.

I am not worried about that. He will serve his full term. I won't be surprised if he outlives Trump.

Not at all. If that morbidly obese, orange blob who was only three years younger than Biden didn't die in office, despite scarfing down Quarter Pounders and KFC daily by the bucketful, Biden, who's fit as a fiddle, certainly won't.

The red button has been changed from ordering a diet coke to summoning a random Trump family member with the sound of sad trombone

Not really.  I was more worried that Former Dear Leader would get fried chicken grease on the Oval Office carpet.

Not particularly. There is no such button.

He had the red button removed. Trump used it for staff to bring his Diet Coke on a silver platter.

Not really because Kamala will become president and hopefully conservatives commit suicide after that happens. 

Or the red button that would cause him to drown in diet coke.
