Sometimes our bodies are not quick enough to fight them off. Sometimes you get a cold quickly and sometimes you don't get one at all. It all depends on ventilation. The more air movement, the chances of getting a cold are slimmer. Hope you don't get one.
People get more colds in the winter time because during the winter people like to snuggle more.
When people snuggle more, they spread more germs to each other. This causes them to get sick more often. I think that colds are caused by bacteria. I think that when I eat jelly beans they taste the same when I block my nose or I don't . In winter in doors the air gets germ, because people are inside a lot.
