Common sense just says that this whole situation is not worth a damn. Valieva is an amazing figure skater and we have seen her amazing performances over the past few years. If you haven't completely "changed your shoes in the air" (although the speed of your metamorphosis is impressive) you will agree that the reasoning "all these years she was stuffed with this magical drug (which is undoubtedly capable of turning any Karen Chen into Valieva) and that's why she became so awesome" is disgusting, sick nonsense.Common sense and lack of naivity.
If we discard all this formalism and speak from the point of view of common sense, you will not be able to explain to me a simple question - why would Valieva take this "doping"?
