Temperature and blood pressure

Being off sick with a flu has given me a chance to ponder the various ways people in different countries deal with being ill. As all Danish people (possibly all continental Europeans), I check my temperature regularly when I’m ill (yesterday I reached 39.5°C [= 103.1°F]), but Phyllis claims that people in this country don’t bother – more often than not, they don’t even own a thermometer. As she says, what would I do differently if I didn’t know my temperature?

In Georgia, people don’t check their temperature either, but instead they check their blood pressure, and they thought it was weird that I didn’t know my normal blood pressure.

I believe I once heard that people in China do something different when they’re ill, but unfortunately, I’ve totally forgotten what it was. Does anybody know?
