My buddy Dan has a wee bit of teaching by example at his place.

Wear yer helmet! This was a total accident. It could have happened to anyone. Ivan made a right turn in to Fred and launched him into the pavement. I saw Fred’s helmet last night and it’s smashed. If he wasn’t wearing it, we would have been spending time in the ER instead of beer and pizza at the bar.

I know that it’s Tour De France time, and that gets a lot more people out on their bikes. Heads & brains are irreplaceble, everyone. A helmet may be the best cycling investment you could make.
