I'd believe it, but I think arguments could be made against your points but still

I'm not saying that he'll be cheating death. When it's his time it's his time regardless of money. I'm just saying the treatments he's recieveing is probably stuff that insurance companies don't even bother to pick up the phone for you know?

I can't explain without getting into full conspiracy theories about why I think this, I have no studies on hand to back this but I have no doubt rich people get better treatment. Add on that a world leader of, arguably, the second most powerful nation (at last time of counting. Next year will probably knock em down a few pegs)

The easy argument is we don't know because we're poor. Relatively. I'm not a doctor I just assume a corrupt world leader won't be worrying about hopsital bills while hiding one of his many yachts.

Just speculation

No he's got the best treatment in the world. He's paying for extended life for sure

Tbf he's not snubbing them he's just slowly dying of cancer
