I've never understood why people get so upset about being forced to wear helmets. Why take a risk when it comes to what is arguably the most important part of your body? Even if you're a perfect cyclist who will never fall over (and will never suffer any kind of mechanical failure, like the seat on my bike that broke off while I was riding down a hill) it's still a sensible precaution and worth some minor inconvenience like having to bring a helmet with you or leave it attached to the bike.
