S. Jay Olshansky is a professor at the University of Chicago and is an expert on the effects presidency has on aging.
He sat down with Newsweek recently to discuss how Donald Trump is likely to age during his time as POTUS if he makes it through two full terms. Because Trump entered the presidency as the oldest person ever to take the office, the effects on his health are likely to be more drastic than for others who've held the seat.
"Because Trump is 71, his risk of death is significant'y higher than if he was in office at 61 or 51, there's no question. His risk of death today is double what it would have been had he entered at 64."
Olshansky credits Trump's wealth and the incredible healthcare given to each POTUS with extending 45's life expectancy. The average man with his physical stats has a life expectancy of about 84 years. Olshansky puts Trump's at about 87.7. So, in Olshansky's opinion, Trump is likely to live long enough to serve out two terms, it's just that he'll likely look very different when he leaves office.
Olshansky does have one piece of advice for Trump, though, if he wants to survive what he presumably hopes would be two full terms:
