I don't think that's healthy point of view. Helmet has saved my skull once and a close relative of mine had an accident that would save him lots of pain had he wore a helmet (he hit a curb with his head when falling down). Comparing cycling with walking on foot is, well, unusual to me to say the least. Of course, you can fall down walking as well, but as a cyclist, you are faster and you are sharing the road with other bigger/heavier vehicles. I would not dream of going on a bike to cycle in and around my town (somewhat hilly terrain, relatively narrow roads) without a helmet.
