No one is arguing that under a very narrow set of circumstances a bicycle helmet MIGHT reduce the severity of an injury.

No one is arguing that tobacco use is unhealthy at least and deadly at most.

I am offended by second-hand smoke. I am NOT offended by seeing someone riding a bicycle without a safety helmet. I do not feel compelled to tell EITHER of them how to handle their health concerns.

Until every tobacco product is banned under law, leave the bare-headed folks alone. First things first. People worry about the wrong things sometime.

Isn't there a special Helmet Thread?
