the threat of illness or death doesnt stop these guys- look at how many walk around long after having competed with tons of weight putting stress on their hearts. look at that pylon nasser. they have body disorders that make it impossible for them to be 'normal' looking. the only time they seem to trim down is when its too late.
that being said i fear dan hill has the aids, or some variation of it. like the type that eats your muscle, and makes you ugly.
