Good on you! Head trauma, even if it seems OK right after the accident, is nothing to take lightly. Always good to get it thoroughly evaluated.

A good friend of mine got clipped by a trailer while on a road ride. The first instant his fellow rider realized something happened was when he saw parts of my friends bike helmet fly by in his peripheral vision. My friends helmet was totally shattered but he didn't suffer permanent brain injury. He did spend a week in the hospital from other injuries, but recovered to ride again.

His experience definitely made me a believer in bike helmets!

Over time, I have worn a helmet more and more frequently, in a greater variety of situations and pursuits. This has been helped along by responding to accident scenes where a helmet would have probably saved lives.

I started out wearing a construction grade hard hat while caving -obviously useful because you are always scraping your head and you also need a place to fasten your light. I bicycled and climbed for years without a helmet, but I eventually changed.

My oldest daughter suffered through two hospitalizations resulting from injuries incurred while riding sans helmet. After the second event, I told to wear head protection. "It's too dorky," was the response, and she gave up cycling. Later, after a career in the ER, I notice that her kids do indeed wear bike helmets, which are available in an increasing variety of protective and attractive styles - so much for "dorky."

Fire Captain: "Mr. Magnet? Your wife doesn't want to get in the ambulance."

My words: "Dear, I think you better get in the ambulance."

My tone: GET IN THE $&£€ING BUS RIGHT NOW BEFORE I LOSE MY #¥%^.

My thoughts after I heard myself say it: "I do not usually speak to my wife that way."

My wife's words after I said it: "Okay."

No arguments on that one here. I've lost count of how many cyclists have jumped a light (and I'm on a bike and stopped at the lights) right in front of me. Interestingly they are usually dressed like they are doing the Tour de France. Their Guardian Angels seem to be on the job. As yet no one has been offed by a honking big lorry which is either a very good thing or dashed annoying.
