There are quite a few of us that are exceptions then?
Please forgive my scepticism, but I'm just not buying what is being offered. I simply don't accept that aircraft cabin air and environment are inherently any more "risky" than any other environment where human beings cluster together - in fact, it might be argued that there is a lower risk due to the filtering process. To change my view on this would require something more concrete than a Chinese Doctor and some anecdotal "evidence".
