not disagreeing with the wear your helmet thing, but there's no way the whole 10% is from motorcycle people alone, there would have to be an awefull lot of accidents to make the average go up that far, considering how many people are in the state., that number could be in the hundreds of thousands...maybe they are counting each body part as an individual..so one person could realitivly be 5 or 6 parts...heart, lung,liver,kidney,kidney,ect
wear your helmet
