as an alternative test as to whether or not you need to wear a helmet, stand outside beside your bike with a a raw egg in your hand while holding onto the handle bar. Drop the egg. Look at the results and pretend the egg and its contents were your head and brain.
Be aware that different brands of helmets are different shapes. Some are more oval while others are more circular. Pick one that fits the shape of your head.
As for looking dorky- I would much rather look dorky in my helmet and be fully functional than have to spend the rest of my life looking cool but with the brain skills of a slug or a vegetable.
just sayin.....
