The Olympics are cool.

Here is one of my favourite images from an Olympic games. Americans Tommie Smith and John Carlos gave a 'black power salute'. Smith later claimed it was a 'human rights salute'. A brave action at the time. Both athletes were ostracized upon returning to the States.

The Olympics in London are coming to a close. Although the medal table highlights the gap between the rich and poor nations there is much good which comes out of the Olympics. It is a sporting event that breaks down barriers and for two weeks every four years we are all humans united peacefully. The story of Sarah Attar is a perfect example of the good that can come from the Olympics.

Bring on Rio '16!
