Sebastian Coe, the president of World Athletics, said on Wednesday that track and field’s governing body had agreed to introduce the testing to keep the “absolute focus on the integrity of competition”.

That's the point I was addressing. The Olympics have change a lot. If they want to talk about integrity, they've already lost.

Maybe we should be more unisex, add more shooting, chess, card games, e-sport, Formula E, etc.

This is why I don't watch the Olympics anymore. They are a parody of the original.
