No, for sure not. or not yet 

At first,  yes. But now, I just shrug it off.  As we say in spanish: "Lo que no mata, engorda" (that which does not kill you, makes you fat).

NO, I am better for living here........  still smoking, maybe more, but at 10% the cost........  drinking much less often, 'cause not hanging out with the same riff raff after work,  and eating much healthier foods here than I did at home.........  way more fresh stuff, less meat, more delicious fruits and vegetables............  happy to have found this healthy smorgasbord.

I've just crawled out of my sickbed after 30hours down with what I suspect was a nasty attack of food poisoning, hot and cold shivers, feeling incredibly cold while my body was warm enough to roast chestnuts on and the usual VERY frequent toiletry visits. That was 'cured' by 30hours bed rest, no food (at my own insistence) and some medicine from the pharmacy that my wife got for me. So no,  I don't think I'm a hypochondriac esp as that was only the third illness I've had in two years.

Not paranoid at all...but it tooks years for immune system to become used to everything that floats around here, really years and still I pray that during the cold Dong Bei winter months I don't come down with pneumonia, bronchitis and the like.  A little paranoid, I guess, with all the spitting and all the tuberculosis on the loose around here.  And things like that.

the opposite. when the locals have the slightest problem they spend days taking in horribly tasting "medicine". I am some kind of super human who can survive even the common cold without medicine. I can even be naked in a room with A/C and live to tell about it. The Chinese culture is in my mind very hypochondriac, the integration of food and medicine means that being sick is constantly on the minds of the Chinese. 

Opposite. "Pff, this can't hurt me"
