1. You don't have to answer dishonestly to trick questions ("Is there too much salt in the food", "Am I looking fat?")
2. Performance anxiety is much lower (or at least less visible)
3. You can always excuse yourself from a meeting.
4. Your chances of promotion increase (depends on 'how' you look at your boss)
5. You get a chance to miss your wife.
Geez... I need a life.
