Friends and family can have a huge impact on whether you take part in sports, and which sports you choose.
Parents can encourage their children to take up sports
Some sports may need special clothing or equipment, so its usually the parents who pay for these.
Many children are taken to and from activities by parents
Most people have a group of friends they spend most of their time with.
This group is known as their peer group.
If all your friends play football, you are likely to play football
If all your friends say sport is rubbish, you are less likely to play it.
