Why Not Wear A Helmet??

May is Motorcycle Awareness Month so I see very fitting talking about Helmet Safety.  Seems like everyone I talk to says they don't like wearing a helmet.  Well, I on the other hand enjoy having my head attached to my neck.  There are only 2 states who are 100% approved for No Helmets.  Those two are Iowa and Illinois.  Michigan and Florida have partially adopted the law, but they require the driver to be 21with proper medical insurance.  Florida requires a driver in an Automobile to wear a safety belt at all times; why not a helmet?
