What do Doctors do on their day off?

Starting with $100,000/pa, one can't really get into sports and
hobbies for the rich/wealthy:  polo, yachting, serious collecting,
etc.

That looks like the information, but I always wonder how accurate such
surveys are.  If you present people with a questionaire listing
activities, there is a natural tendency to respond "correctly": 
listening to music and attending concerts/theater/ballet, fine food
and wines, etc.
