One of the hobbies the cavemen had was

In all history, when men have had free time they have turned to a hobby for pleasure. The cavemen were our first known creative hobbyists. (11) In the free time after the hunting and fighting necessary to keep them alive, some turned to drawing. They drew and scratched on the walls of their caves crude pictures of the animals they knew and the battles they fought. From the dawn of history to the present day men have left records of the fun they have had "riding a hobby".
    Gorge Washington was one of the first busy hobbyists in American history. (12) As a youngster he was interested in mathematics. This interest led to his early years as a surveyor. (12) His early agricultural experiments added to his success as a farmer. He found time to design furniture that added beauty to his home at Mount Vernon. His study of evening skies with a primitive telescope increased his knowledge of his own world. He also made a collection of varieties of tea.
    (13) Today hobbies are more important than ever. We have more leisure than we have ever had in the past. Interesting hobbies can be the best answer to the question of how to use these hours.
