Athletes going to China are concerned about pollution. Air pollution mostly. Smog, if you will.
They are concerned about the health effects of such pollution. And American cyclists showed up wearing black masks.
And yet, cyclists, at least as much as any other athlete, are the ones at the forefront of the doping scandals.
In other words, they don't have a problem with injecting their bodies with all kinds of abnormal/foreign substances- but they're afraid of the deleterious effects of a little smog?
Does anyone else see the irony? It's comical.
