Olympic and Paralympic Values: Courage week
BBC World Class go back to Bishop Okiring School in Mount Elgon, Kenya to re-visit Alex - a pupil who contracted polio at the age of four.
We featured Alex in an assembly last year entitled 'Overcoming obstacles'. Now 21-years-old, Alex is in his final year at school and says he wants to train as a lawyer when he leaves.
We look at how Alex is coping with his disability for 'Courage week', part of the Olympic Values series.
