You are correct. He didn't have more than 2 yrs to live many moons ago. What a nation. Run by nothing more than thugs from top to bottom.
I have heard this over and over again and it makes perfect sense since few live long lives on dialysis. Especially when you are on the road and in hiding as OBl was. It's just common sense.
