Well, of course I defer to your superior training and skills in evaluating the health of people

. Trump is an accident looking for a place to happen, health-wise. No one can predict the future, but, like most experienced physicians, I know possible trouble when I see it. Sure, Biden could be dead before 2024, but my money is on Trump in that race.
Here's one published evaluation of the two old guys. Biden's life expectancy is longer due to not being obese and being physically active five days a week.
Lifespan (independent of medical
history)
• Biden life expectancy estimate using a
combined risk factor approach = 96.8
years (average is 87.4 years)
• Biden probability of surviving a fouryear term as president = 95.2% (average
is 82.2%)
• Biden probability of surviving to age 85
years = 66% (average is 61.2%)
• Trump life expectancy estimate using a
combined risk factor approach = 88.6
years (average is 86.2 years)
• Trump probability of surviving a second
four-year term as president = 90.3%
(average is 86.2%)
• Trump probability of surviving to age
85 years = 60% (average is 55.0%)
