A hobby is a special activity that you do in your spare time. Hobbies are of different kinds. It's hard to name all leisure activities, entertainments and hobbies practised by people. Collecting stamps, coins , pocket calendars and the like, listening to music and reading a book can be called indoor hobbies. Drawing, painting , photography, writing poetry and the like may be called both indoor and outdoor hobbies. Gardening, hunting, fishing , swimming and bird-watching are all outdoor hobbies. Each individual selects his hobby based on his interests and tastes. Hobbies not only give a sense of excitement but also educate. For example, collecting stamps or coins of various countries, no doubt, gives pleasure. At the same time it helps us to learn the geography, history and culture of those countries.
