I fell off my bike Friday.  There's nothing more embarrassing than falling off when practically stationary and my kids doubled over in laughter.   I bought some fancy pedals with shoes that click into the pedals.  I had one foot locked in and was trying to get the other foot into the pedal.  I accidentally moved the pedal forward and somehow clicked the shoe in and with both shoes clicked into the pedals, I lost my balance and fell over.

I'm glad I had my helmet on as I hit the pavement pretty hard.  I didn't think anything of it until yesterday when I still had a headache and a sore neck.  One ER visit and a CT scan proved I was okay, but I still have a headache and my neck is sore.  ER doc said if I hadn't had my helmet on, I'd probably have a concussion.  DH has banned me from riding until further notice.

I'm still not a big helmet fan, but I know enough that a helmet will at least protect your head from being cracked open on the pavement if you land on it.  I'd like to keep my skull in one piece.
