I understand your fears, my brother doesn't like to wear his helmet either...however he is a big boy and understands the dangers. I would not like to imagine the worse but also would not miss the good times we have riding together! Your example is the best teacher not harping on him.
One observation about ATGATT....A lot of riders who preach this (I mean no offense :bow1 seem to ride a little more aggressive just because they believe they are protected. I know when I wear the full face helmet I don't notice the things around me as much and I get "surprised" sometimes by cars coming up around me. So sometimes the less I wear (gear wise! ) the more careful I am!
Just my thoughts....
