Michael Jackson has "potential fatal health issues" according to this Fox News report. Author Ian Halperin - who, it must be noted, has a Jackson biography ready to hit the shops - says Jackson suffers from the genetic disease alpha-1 antitrypsin deficiency and as a consequence is going blind and is in urgent need of a lung transplant. So much is written about Jackson that it's hard to know what to believe, so I'll take this with a grain of salt for now.
