When are you going to Retire?

I read a great article today while on the plane from Philadelphia to Houston in the United Hemispheres magazine on James Patterson, the former advertising guy turned prolific writer.  While I haven't read any of his work he certainly is an intriguing guy, one quote in the interview stood out, he was asked in the interview when he was going to retire, his response "I don't like it when people ask me when I am going to retire.  You don't retire from play, you retire from work.  And I don't work."
