I'm just amazed that, for as long as I've known folks with CP, I never knew
that the anger problem and the sensitive startle reflex were so common.

Probably a dopey question but that never stopped me before!  :)  Is it
possible to desensitize yourself to loud noises, etc., at least to some
point?  You know, YOU do the loud banging, have someone tap you, etc. in a
controlled environment and condition your body not to react so much?  ANYONE
is going to react to sudden surprises, but I mean just to "ameliorate" it to
some degree, as someone mentioned.  Just curious...
