I just fell today, my foot got tangled up while I was trying to get off the bike. At work. In front of a dozen people. And in front of the security camera, which has someone watching live feed. No, not embarrassing in the slightest.
Fortunately I fell flat on my back, fortunate because I was wearing a backpack with two changes of clothes inside, which made a nice soft cushion. I'm not sure if I bopped the back of my head, between thickness of the backpack and the helmet I didn't feel a thing. However had my backpack not been 6 inches thick I would have a headache right now, because my head did go backwards uncontrolled.
All in all, my pride was all that took damage. The only thing for the bike was the seat was turned fully sideways and I had to realign it.
