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.

I have never heard a doping offender say he felt good about doing it. Not a single one. Some athletes justify their actions by saying it enabled them to afford a bigger house or a better car. But they are never really happy. They know that they are not real winners.

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

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

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.

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.
