Many years ago I was leisurely riding my bike in a park-- no one, no cars around me. I made a quick turn to go in the opposite direction but made it too tightly and lost my balance. Fell off, rolled down an embankment and head smacked into a tree. Fractured my wrist and saw stars for a moment. Rode home and went to the ER for arm. Wish I had a helmet for the head and the arm! Please, no wisecracks--I do know how to ride a bike--just not very well.

Sounds like you got off easy! Could have been FAR worse. Better a broken wrist than a fractured skull.
.
I've fallen off motorcycles, bicycles, skateboards, roller skates, ice skates, surfboard, belly board, ladder, tree and logs.

In two cases I would have been killed if not for my excellent Bell helmet, and because of it I had no serious injuries.
Not even the helmet was damaged! Kind of scraped up but only cosmetically affected.
The sides of the helmet come down just close enough to the shoulders to not be in the way but support the top so as to transfer top end impact to the shoulders which relieves the neck of taking all the impact.

Head injuries are always in a special class for medical workers, and a good helmet is a total Godsend to prevent them.

In the early days of football they used leather head coverings that were adopted from aviation gear, of practically no use for impacts.
Eventually they went to rigid helmets that are universal now, but football players still manage to achieve head injuries.
