I hopped on a bike for the first time in ~20 years a few years ago. Fell off the bike at one point, going pretty slow in objective terms but faster than I should have been given my experience - got a concussion and broke my nose as well as got two pretty deep cuts on my hand and ankle. When I took the helmet off the front had split open from the impact. What was a quick exam from a doctor who was on the trip could have easily turned into a ruined vacation with days in the hospital or worse, and this was a slight downhill grade where I was barely pedaling. The thought of falling off a bike without a helmet at any appreciable speed should be very frightening.
