How can you tell.....

Interesting observation--you may have a good point. Doesn't change the fact that riding w/o a helmet is reckless, however.

picture your brain as an egg and then drop said egg on the sidewalk. That is your brain without a helmet.

I am pretty unabashed about calling anyone who rides without a helmet an organ donor. it's a good thing whhen they take themselves out of the gene pool voluntarily.
