Hobbies

Hobbies become a necessary part of life for a lot of people. They give us a change from the daily routine and are a means of selt-expression, helping us to live in harmony with ourselves

Hobbies can possibly be divided into several categories. There are, for instance, hobbies which most people consider useful These may be gardening, house decorating, making clothes, keeping bees, cooking and others.

The second catcgory of hobbies includes those connected with collecting objects of interest - stamps, picture postcards, matchbox labels, badges, model cars or ships, coins etc. A large number of peoplc choose hobbies that have something to do with the natural world. They keep birds like budgies or canaries and also dogs, cats, goldfish or exotic animals like snakes, iguanas and spiders. Nature lovers grow house plants of various types from common violets to rare kinds of cactuses. Collectors and nature lovers are one large world brotherhood with their own magazines and international friendships. Anyhow, we have to admit that such hobbics take up a lot oftime, money and space.

One more category of people are those who enjoy the arts: those who go in for singing, competitive dancing, playing on the stage, music-making, drawing and painting. Photography has become very popular as well. Most of these pastimes give people a chance to get together socially

Finally, there are hobbics which are good for keeping fit and broadening one's knowledge and mind: they are occupations like travelling, camping, rock-climbing, doing sport and playing different games. These hobbics are good for meeting people and sharing fun with them.
