I was still young when I missed Beijing. I was favourite to win a medal but I knew I had time. My coach advised me to stay at school and finish my exams. Even if I had gone and won the Olympics, I might not have handled the pressure. So I moved on.

Going to the Olympics as a Maasai I want to make them proud because, after the warm welcome they gave me when I went back and being their leader, I want to also be the warrior in the Olympics. That will be something good because that will be the first Olympic gold medal for the Maasai.

We exist in this weirdly schizo culture, where sex is everywhere in the media, and yet, at the same time, you don't sit down and have a conversation about what you did in bed last night with your friends. Despite the ubiquity of sex, it's still a taboo when it comes to day-to-day conversation.
