I used to stand up in the front seat of the old Chevy with my arms behind the seat to sort of hang on. Once the brakes had to be slammed on and I hit the dash. The chrome "Chevrolet" on the dash embedded on my face.
Awesome! I had almost the same thing happen. In our old Jeep Cherokee, we would stand on the hump between the two front seats just holding on to the seats. Once, my mom slammed on the brakes so hard for a red light that I went flying and broke the CB off of its mounts with my head. I was unharmed fortunately.
I never wore a helmet while biking,of coarse such a thing wasn't intented when I was a kid. And if some one did wear one they would have unmerceifully been harassed. When playing tag I used to hide on a garage roof that was two stories high. When the person that was it would go past i would jump off and go touch the goal. We used to always play takle football on a paved street with no equipment.
