Music producer Timbaland is so afraid of germs he flies around the world on one private jet. The hip hop music-maker refuses to expose himself to other people's illness and bacteria by flying with commercial airlines. He explains, "Your health is more important than anything else. I fly private so I can stick to one aircraft rather than have to sit with a bunch of people coughing and sneezing: the way I know what I'm dealing with. "But you can't get better is you don't rest, and I've been going constantly, non-stop."
