I was walking to class today. It was a sunny day, but the temperature reached to around mid 30s, and on top of that, it was extremely windy. Needless to say, it was cold, and I was freezing. I passed by a group of girls and one guy. The guy was just wearing a plain t-shirt and jeans, while carrying his jacket. One of the girls yelled at him saying that he needed to put his jacket on or he'll get sick.
I thought about it for a minute. "Put your jacket on or you'll get sick." I can't tell you how many times I've heard people say that.
Now I'm not an expert, but I could have sworn that the way people get sick is through germs. How do people get colds? I'm pretty sure someone got it from someone that is sick and not from the fact that someone decided they wouldn't wear their scarf today because it was 20 degrees outside.
It makes me wonder. Can you really get sick just because it's cold outside?
