Dress properly to avoid freezing
What is this nonsense? Are people stupid? Some are going outside with no cap on and only a thin coat when it is so cold out. I have even seen some people with shorts on while the temperature is lower than 20 degrees.
I went to a festival in Iowa once and I couldn't enjoy it because I had pneumonia. It was the middle of May. The weather was sunny and was 83 degrees. My son had to keep cooling my head down from the high fever I had. The doctor said I could have died.
Just think how much easier it is to get sick and seriously ill when it's this cold outside and you are not dressed properly for it.
