Well the experiment is over.  When I retired last May, I decided to let my hair and beard grow.  I figured after 35 years I deserved a little slackness.  Last Wednsday when I pulled into the garage on my Norton, my wife was standing in there searching for something.  When |I took off my helmet, she grinned at me and said...""when it gets a little longer you can put your hair in a ponytail and really look like an over the hill biker.""  The very next day, I got a proper haircut and a good trim on my beard and moustache.  Now I just look like an over the hill Chief Petty Officer...
