I don't normallyrespond to ranting posts such as yours, but as you posted immediatelyunder my post a day later, ambiguously, you may be referring at least partly toit. If not, all I can say is that your credibility as a scientist iscast in doubt by your unsubstantiated opening post in whichyou stated:

“I can only concludeUSA people DO COUGH DIFFERENTLY”.

To make matters worse,in your last post, you accuse other posters of “posting yoursnide and uninformed comments”

If you are referring tomy post, my additional  comment is that my reported experiences arescientifically valid empirical observations and experience over manyyears.
