Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

just because we don't think it's cool, or it fucks up our hair, or it's a bit of an inconvenience or discomfort

I don't want to get involved in this debate because I've unwillingly had this argument several hundred times but I wanted to point out this is a bit unfair... some people choose not to wear helmets for reasons other than this (i.e. one of the reasons I don't wear one is because drivers tend to give female cyclists more space, and you look more obviously like a female cyclist if you're not wearing a helmet - yes it's sexist and lame and it pisses me off that people assume female cyclists need more space but at the same time... that's how things are).
