I've been riding bikes since my childhood. I am extremely cautious when riding, I try to give 110% attention to the road ahead, cars, pedestrians and possible obstacles and dangers. I come home not only physically tired but mentally tired too. I had my share of accidents since childhood, one major accident but that was when I was 6 or 7 and caused by stupidity of that age. Lets face it, all kids at that age do stupid stuff. 3 days ago I bought my first road bike. What a step up from a MTB if you are not riding in dirt. On monday night I took it for the first ride. Years of experience, 45 minutes on the new bike and one nanosecond of distraction and I found myself in the air. Landed on my right hand and my head, finally landing on the opposing lane! Luckily there wasn't a car going fast in the opposing lane, or I could be pancaked. People stopped the traffic to help me, luckily I wasn't hurt too bad and got up fast. My wirst hurts, a lot, but hope it'll be fine. There was a lump the size of a small egg on my wrist when I came home. But, if I wasn't wearing that helmet, I'd paint the pavement red for sure. I don't think I could survive such a blow, even if I did, I probably wouldn't be the same. You know what I mean. No matter how experienced you are, how careful you are, how lucky you have been, your life can change or even end in 1 second. My cyclist, motorcyclist, and working in hard hat area friends, do wear your helmet. I know some people that doesn't wear helmets because it doesn't look "cool". I hope they don't have to figure out even a Hello Kitty helmet is way cooler than a casket.
