Didn't he just lose a family member? Anywho, not everyone is built to fly that close to the sun. I'm a controller (accounting) so I'm right under the cfo and under my staff, I'm currently directing an audit, leading implementation of new software that goes live in April as well as hiring for new positions while watching the budget of a million dollar construction project. Not everyone wants to deal with that and I totally understand it because you are responsible for so much. A person can get burned out by that. Seems like he realized that the spotlight was something that he didn't really want.
