I think we need helmet laws for legislators. It's pretty obvious to anyone that being in goverment causes brain damage. So they should be required to wear helmets to protect themselves.
A free adult should be able to make their own risk decisions. We can't let government use fear of high health care costs to curtail this. What's next motorcycle helmets, bike helmets, ski helmets, jogging helmets, soccer helmets, dog walking helmets...
BTW I always wear my hemet, I feel naked without it. Once in awhile I take it off during bike week when stuck in traffic. It's my choice.
