Of late, I've developed a quite nasty cold. Runny nose, sore throat, cough, raspy voice. Still, I'm expected to show up for work. I've been drinking a lot of berry tea which soothes the throat a bit. Someone who goes to the church we've been attending suggested to me that the air pollution here makes colds worse. A couple other folks suggested I have annual flu shots. One of my students gave me today a bottle of homemade lime tea - which she says should help.
