I'll start off by saying, I am an absolute believer in wearing helmets, young and old. I think it's especially important to teach children to wear them, both by having them wear it, and role modelling by wearing one yourself.
Having said that, I have an excellent ability to see both sides of a situation. Even though, I disagree with the logic, I can somewhat understand the reasoning behind not wearing a helmet. Perhaps it's too hot? Too expensive? Not cool enough? You just don't think you'll ever fall, and therefore it's not necessary?
In places without helmet laws, this is still the choice of the individual. I might disagree with the reasons, but I can at least understand where the thought is coming from.
What I don't get is why people bother to wear a helmet with the chin strap undone? This is something I noticed while running on the paths yesterday. There were numerous inline skaters, and a couple cyclists doing this.
Okay, so you have everything that might be considered a downside of wearing a helmet, but with the chin strap undone, none of the upside - such as saving you from brain injury or death.
Why? This, I just don't get.
