Soccer is the most popular team sport worldwide and can be played by people of all ages and skill levels. It has a long history dating back 3000 years and involves kicking a ball into a goal. The basic rules are that teams have 11 players, games last 90 minutes, and goals are scored by getting the ball fully over the goal line. The field dimensions and positions of players are also standardized. Soccer provides health benefits like improved cardiovascular fitness but also carries safety risks like injury that can be mitigated with proper equipment and care.
