&gt; Also, I&#x27;d like to see some stats on your &quot;not very likely&quot;. In 20 years of adult riding, I&#x27;ve fallen twice at low speeds hard enough to crack a helmet. And that&#x27;s not counting the time as a kid I knocked myself unconscious on a low-speed ride.<p>And in 28 years of both adult and kid riding, with some years totaling over 3000 km, I&#x27;ve fallen several times, even cracked a couple of ribs, but never once hit my head. See that&#x27;s the problem with anecdotal evidence.<p>&gt; I clip my helmet to my bike<p>Do that in Rome, you&#x27;ll come back to find none.
