>>helmets deteriorate at 2.5mph.

as other replies have pointed out, skulls deteriorate (severely) at less
than 13 mph.  my real point, tho, is that i don't agree with your claim 
that no helmet can withstand impact stresses > 13mph.  personnally, i've
put a bike down at 60-65mph and ended up with some substantial battle
scars on my bell star II and leathers for my efforts.  i ended up with
a hell of a headache and 20 minutes of nap time on the shoulder, but am
otherwise no more brain damaged than before.  try that with your bare
head or $30 no-name helmet.

the bell bumper sticker says it best of all:
"buy a $10 helmet for your $10 head"


(standard disclaimers; 
plus, i have no connection with bell other than as a satisfied consummer)
