20. Cold weather gives you a cold

•THE TRUTH: Germs are spread by touching the eyes, nose, and mouth, when germs are on your fingers, or by inhaling droplets of germs expelled by a sneeze. Cold weather does allow germs to survive longer, but cold weather and viruses are not connected. Another explanation is that people are in closer contact (inside with each other for longer periods of time) than they would be in the winter.
