[Tigers] Wilwood brakes

[Jay Laifman]

Thanks for all the responses!  I should have included a smilie.  I was just
having fun with the statement, thinking of my college Physics courses.  Of

the same.  Its that the negative acceleration of the skull is dramatically
different, resulting in of course a much greater force for the brain in
hitting the ground situation. ;-)
