Never get a flu shot. Do you know what's in a flu shot? I know they contain mercury - a neurotoxin that damages brain and nerve cells plus more chemicals our body does not know what to do with. I read that 36,000 Americans are killed every year from the flu.
Government statistics lump flu and pneumonia deaths together, but flu deaths are only a small fraction of the total. In 2001 the total number of flu deaths was 267
I feel it is like everything else - Follow the money. Eat good food, drink water and get your sleep.
Exercise helps too and deep breathing to get oxygen into your body. Take responsibility for your own health.
