After 15 days of voting, here are the results.
Those who read this blog at least, wear a helmet all or most of the time; 13% don't
In retrospect, I probably should have left the “saves lives” option out, because it split the vote. If you add the top two together, most feel that a helmet gives considerable protection.
Clearly, although many get passionate over the helmet issue, only a relative few want to make them mandatory. The majority feel it should be a personal choice.
My thanks to all who participated, and commented.
