I have a rotten chest cold from the bloody weather.....40 degree heat one day, then 20 degrees and rainy the next does not bode well. Especially sitting in aircon all day.
Ohhhh! That happens there? It does here too. Every fall and spring I deal with the same kind of thing with my kids. ARGHHHHHHHH!!
I don't like A/C for that reason, but it's necessary.
