Something is swelling up among our athletes. Many of them are frustrated, everywhere in the world, and they are looking for a way out. Either they start doping themselves, or they give up the sport. Or else they stand up and demand that those who have the power to should change the system.

Being skeptical is part of my job, to question every amazing achievement. That's always there. But I am also capable of turning down the cynicism. The basic idea of sports, the fairness, the competition, remains a beautiful thing.

In order to expose a system though, you need whistleblowers.

When you notice that politicians and the media are after you, it makes you all the more determined to find out the truth.

Education and prevention are not enough when there is a culture of fraud.

The Olympics unite the world and inspire us to be a better version of ourselves. The competitions motivate the spectators, and the athletes' message is: You should have more confidence in your ability to achieve things, you should dream more.

It's not enough to just test athletes. The athletes themselves need to fight for their right to compete against clean athletes.
