I think it's as copium though. He's very concerned about his own health, we have many proofs about that, and it's obvious he's a paranoic, but I don't think he's more ill than any gramps at 71, and he has the best medical support availiable in Russia. But yeah, I don't see him surviving another ten years. Not because of the said illness, would it be cancer or Parkinson's, but because his dick wiggling in Ukraine put many of his partners and their assets at risk, and his authority is wanishing with each new day this war lasts. I'd be very surprised if he'd die due to natural causes. Don't quote me on that, but if new reelection and a coming mobilization won't change anything, he'd have all chances for his bunker to be welded shut and flooded. Yet another sort of copium, if you think about it, but the one I personally can bet at, learning about a den of snakes he collected around him.
