When most people think about London 2012, it's often about issues such as transport, security or the elite athletes themselves. But there is a side to the Games that can often be overlooked. Sport has the power to change lives and empower young people. Sport can bring schools and communities together, promote a healthy lifestyle and give young people an incentive to attend school regularly. It was for these reasons that I became an ambassador for International Inspiration - London 2012's international sports legacy programme - in 2009.
