I am far from medical expert, but i tend to listen medical experts (unlike health minister of U.S.), and consistency of all their views tells me, that unless Trump changes his diet and habits radically, he is gone in a year.
And i am skeptical he would change anything. He will eat medicine and supplements for sure, but that's all too little and too late.
He is not not going to start to exercise, and i am not even sure if he would benefit from it anymore, as it could strain his body more then he can manage.
I am surprised that i haven't found a bet about this in polymarket yet.
The health presidents are top secret until they die. Joe Biden looks sicker; he was always falling, and I thought he wouldn't complete the first term. But with the help of some of the best physicians he completed it and is still alive until now. He has claimed that he has never felt better in his life, and we will have to accept it.
Vice President JD Vance recently said that he is qualified to become the president if anything happens to his boss because he has gained so much experience from Trump. I am not a medical practitioner, but from my observation, Trump is still strong and fit to finish his second tenure.
Polymarket is known for weird bets. But it wouldn't place a bet on the health or death prediction of anybody.
