Hobby 

        Every person on earth may have at least one hobby, and the British and the Americans are no exception. It can be almost anything a person likes to do in his spare time. Hobbyists raise pets, build model ships, or weave baskets. They watch birds, raise flowers, climb hills, ski, skate, or swim. Hobbyists also paint pictures, attend concerts, or perform on musical instruments. They collect anything, from books to bottles, from shells to stamps.
