Fidel Castro is nearing the end. From the descriptions of what’s been going on with him, I think his problems stem from severe diverticulitis, and have involved a lot of bleeding and peritonitis. I think for this they would have to leave the surgical wound open in any case, letting it heal by ‘granulation’, gradually filling in from the inside, but that Castro’s hasn’t had the opportunity to heal, and he is losing fluids from it.
Basically, there is good reason not to fall in with skeptical people who think Castro was already dead and they’ve just been covering up his death—no, he really has been suffering from something that could suddenly knock him completely off his feet for months and months and then kill him.
If only he had eaten more fresh fruit and whole grains!
