Riddle: There is a man who lives on the 100th floor of an apartment building. Every day he goes to the 75th floor and walks the rest up the stairs. He does not need exercise, nor does he do it for fun. But when he goes down, he goes down all the way to street level. Why doesn't he just go to the 100th floor using the elevator?
Answer: The man is too short to reach the 100th floor button on the elevator.
