I guess they can be dull mundane hobbies too. What do poeple like to do outside of tennis? I love to garden and spend way too much time wandering through my yard planning the next great project. Read primarily non-fiction - currently hung up on the holocaust. Enjoy wandering solo through art museums. I'm addicted to sudoku puzzles and still can't figure out why I can solve the diabolical puzzles but screw up the moderate puzzles. I'm teaching myself to play the piano - doing a rather poor job of it but I enjoy it. Does eating qualify as a hobby?
