The only possibly helpful comments I can offer here are:

1. The old standby re flu - keep your hands clean.

2. The "newly found" report that flu spreads best in very dry conditions. A remarkable, if somewhat puzzling, part of this report is that only the absolute humidity seems to have an effect, so high relative humidity is not required.

So the old advice to "wash frequently" gets the associated advice to "sweat profusely."

Anyone want to pass the chile peppers? I'm too old to work up a sweat the old-fashioned way.
