Thanks for your question. It's a complex problem to understand.
The experience we've had, in speaking with athletes who have chosen to go down the road of doping, is that it has been for differing reasons. If you think about cycling as an example and some of the experiences we've had in that, there are athletes who shared the same view you have as far as never thinking they would do it until they encountered a culture within that sport at the professional level and made the decision at that point in time to go down that route.
Certainly the work we do in anti-doping on the protection of side of things and the enforcement side of things is important and it's effective to a certain degree. But I think the key message is it comes down to values and the values within our sport system in order to create an environment so the young athletes at the playground level, as they move up, can withstand the pressures that may exist to dope, based on the proper values they've experienced in sport before getting to that level.
