banging your head doesn't sound sensible at all and neither does a piece of styrofoam over your head.
if you think this will save your life then you should try banging your head. if you want to wear a helmet
then go ahead. thiis is supposed to be a free country. statistics don't support the need for an
ineffective device and oddly enough they would support that car drivers should wear helmet and
pedestrians should wear helmets and you should wear a helmet to bed as many people die from
injuries from falling out of bed, more than on bicycles. i personally think the bicycle is a safe mode
of transport and that excercise is important to my health. don't discourage a good thing!
