People all over the world are very fond of sports and games. That is one thing in which people of every nationality and class are united. The most popular outdoor winter sports are shooting, hunting, hockey and in the countries where the weather is frosty and there is much snow-skating, skiing and tobogganing. Some people greatly enjoy figure-skating and ski-jumping. Summer affords excellent opportunities for swimming, boating, yachting, cycling, gliding and many other sports. Among outdoor games football takes the first place in public interest. This game is played in all the countries of the world. The other favourite games in different countries are golf, tennis, cricket, volleyball, basketball and so on. Badminton is also very popular. All the year round many people indulge in boxing, wrestling, athletics, gymnastics and track and field events. A lot of girls and women go in for callisthenics.
