Warning #1: “Don’t go out without a coat or you’ll get sick!”
Truth: Colds and flu are not caused by catching a chill or by dejectedly walking home from your girlfriend’s in the rain without your rubbers. Nonetheless, this myth persists, largely because most people get sick during winter, when these situations commonly occur. It may even be possible to think yourself ill. If you dread damp feet, your brain may depress your immune system when it happens.
