Healthy, strong children are petri dishes. Since the beginning of time kids have been killing their grandparents. The older you get the more likely you will contract Pneumonia from any of a thousand viruses, flu, cancer, germs, bacteria or whatever. This one just happens to be more severe. From what I’ve been reading, most folks died within 100 hours after the flu symptoms appeared.
The smart biologist folks need to create a better treatment for Pneumonia. In the end that’s what finally gets us.
Prepare yourself for getting sick and practice good healthy practices. Lots of water, good rest, fresh air, sunshine, no sugar and exercise.
