There are many arguments for the inclusion of Physical Education in the school curricula. Firstly, children nowadays spend too much of their time playing video games such as 'Call of Duty' and 'Minecraft' on their computers or mobile phones. This can lead to a sedentary lifestyle and obesity. Girls especially do not get enough exercise; they would prefer to go shopping on the Internet. Also, some children aren't academically-minded and should be given opportunities to explore other avenues to find out what they want to do in life and if they want to become basketball players, not accountants. Urban development means that children might get run over by a car if they go to play outside in a big city. Furthermore, a study written by a professor in a university in the USA said that physical exercise can improve academic performance.
