The harm done to health by cold weather is great

I live in a place where it can be very cold in the winter and cold weather is very harmful to health. I became aware of this when my dad died of pulmonary heart disease this winter. Pulmonary heart disease is a disease that gets exaggerated when the weather is cold. My dad, who died at the age of 82, was indeed old with a long history of the disease, but the cold weather sped his death. 

During the days when I attended to my dad at his bedside in the hospital, I saw elderly people rushed to the emergency ward on stretchers every day. One of the examples was an old lady who died during my short leave to fetch boiled water for my dad, I saw her pushed in only ten minutes ago.  Most of the patients I saw those days came to the hospital because of the cold weather. Many of them tripped over on the terribly slippery streets clothed with ice and snow and resulted in cerebral apoplexy or heart attack. Some of them broke their bones when falling down.

I think I am still in my prime, but I feel very bad every year when it is the coldest. I have toothache, a sore throat or tongue, just like my state when I am typing all these. I still remember one winter when I studied in senior high school when I caught a very bad cold and tried different tablets to relieve my pain but in vain. I felt so weak that I couldn't even walk. For the first time my dad traveled a long way from faraway country side to where I studied and carried me to a traditional Chinese doctor. That was the first time I took Chinese medicine. After a miserable long week I finally got well, not knowing whether the medicine cured the disease or the virus exhausted what they needed to live.

The weather in winter up here is really bad. I hope people put on warmer clothes and be better guarded against it, especially old people.
