As a kid in the 1990s, I rode my bike everywhere, always wore a helmet (kids I knew did), and here I am today. Of course, my helmet may have saved me from serious injury or death when I fell from my bike while on a hill and landed on my head, cracking my helmet in two. I walked my bike back home, hurting but basically okay, happy that I wasn't allowed on my bike without a helmet. Anecdotes are just a sample size of one and essentially useless... unless the population you care about includes that one person.
