WHAT MAKES ALL PEOPLE KIN
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 games that have firmly established themselves in favour in different countries are golf, lawn-tennis, cricket, volley-ball, basket-ball, 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. Scores of young girls and women go in for callisthenics.

Among indoor games the most popular are billiards, table tennis, draughts and some others, but the great international game is chess, of course. The results of chess tournaments are studied and discussed by thousands of enthusiasts in different countries.

SPORTS AND GAMES POPULAR IN ENGLAND

— What would you say are the most
popular games in England today?

— Well, I suppose football, that
is, soccer or rugger, and cricket.

— What are the other outdoor
games?

— Oh, there's tennis, hockey,
golf, and so on. Tennis is played all the year round — on hard courts or grass
courts in summer, and on hard or covered courts in winter.

— What about horse-racing?

— I should say that is one of the
most popular sports in Great Britain. Then there are, of course, walking-races,
running, swimming and boxing.

— I've been told that there are
no winter sports in England.

— Well, you see, the English
winter isn't very severe as a rule, and we don't often have the chance of
skiing, skating or tobogganing, but winter is the great time for hunting,
provided the ground is not too hard.

— Is there any golf to be had
near London?

— Oh, yes, any amount. There are
dozens of good golf-links within an hour or so of London. You ought to join a
golf club if you're keen on the game.

— I think I shall if I get the
chance. What about indoor games?

— Well, there's chess, billiards,
cards, table tennis... By the way, do you play billiards?

— Well, I do, but of course, I'm
not a professional or a champion, just an ordinary amateur, and not a very good
one at that,
