Michael Jackson: This is the end?

We already know he's a little sick in the head, but author Ian Halperin also claims Jacko is sick in the body and may be going blind!

Ian, who just finished writing a tell-all about Jacko, told InTouch (via Fox News) that Jacko is suffering from a possibly fatal lung disease called Alpha-1 antitrypsin deficiency. Ian also says Jacko has emphysema and gastrointestinal bleeding.

According to Ian, Jacko is pretty much blind in one eye and can barely speak words. Ian went on to say, “He needs a lung transplant but may be too weak to go through with it … [But] it’s the [gastrointestinal] bleeding that is the most problematic part. It could kill him.”

So let's just recap all that. Jacko can't breathe, can't speak, is going blind and is turning transparent!
