Major sports events such as the Olympic Games attract the attention of millions of people all over the world. Small clubs, on the other hand, boost social cohesiveness and so do school and neighbourhood matches. Exercising can have an empowering impact on women or minorities, including people with disabilities. Youngsters experience team spirit. Nonetheless, there are downsides. Some athletes and managers are driven by greed for money and power, so they cheat and manipulate in neglect of fairness. Aggressive nationalism is sometimes fostered. Major sports events, moreover, require major infrastructure investments, and the projects often don’t work out as smoothly as they should.
