I apologize for the helmet reference, but with the alarmist tone of your original post, I thought that not only did you have one, but it was on too tight. I stand corrected. BTW - my friends and I do wear helmets, though not of the tin foil variety. In the wonderful state of NY, we have a helmet law.
In the words of that great philosopher, Rodney King - "Can't we all just get along?"
