Films are very popular in Britain, and about 60% of people between 15 and 24 go to the cinema every month. At home, men watch TV for about three hours every day — two quarters more than women.
Holidays
British people love going on holiday, and have 56 million holidays every year. Most of these holidays aren’t in the UK—27% are in Spain,10% are in the USA, and 9% are in France. Maybe this is because the weather in Britain isn’t very good!
