Actually, Bob lost his dreads before he died because of the cancer that he died of, so because that is false, its hard to believe any of the rest is true. This myth changes, it describes him as having from 9 to 86 kinds of bugs in his hair. So its impossible to know how many he really did have if he had any. The possibility of getting bugs in dreads is no more than regular combed hair. Dreads are a very big part of the Rastafarian faith, keeping them clean is important to them, so I'm sure he kept them clean making it even less of a possibility. I believe that this is myth made by those people that make up all the stereo types of dreads being dirty, but it is a possibility. I don't think theres any way of knowing for sure.
