2 accidents with a helmet & bad neck injuries due to helmet snagging besides that mainly road rash & 2 without a helmet with only road rash, a broken bone in my leg & bruises. Now the only time you'll see me wearing is helmet is when I'm riding proper off-road. On the same note we need to give medium sized quadrupeds road safety lessons.
Anyway you're right, a group of doctors said to me after I was hit by a car "So you'll be wearing a helmet now", I just looked at them blankly & said in a really sarcastic voice "Yeah, a lump of polystyrene on my head would have done wonders for my [broken] leg".
