I experienced things like that back in the 90's and early 00's because my immune system was wrecked at that time. I always had some kind of cold or allergies going on. After I started changing my lifestyle and eating and living extremally healthy, I never experienced a cold or allergy attack again. It's no question people in this country are ingesting toxins day after day, add in vaccines and the immune systems of the average person is a total wreck.
