Ask me why I cycle without a helmet

I am not against bicycle helmets but only for kids and with sports activities like mountain biking, road racing or BMX riding.

The problem lays in the use of bicycle helmets in everyday use of the bicycle.
Mikael-Colville Andersen, founder of Copenhagen Cycle Chic, tells about his anti-helmet opinion and research at a TEDx talk. And I can only agree with him.
