Having survived 86 years of life on this planet, I have my own theory on contagious diseases. The world has always had germs and viruses and other weird unseen dangers. It’s not a safe planet. However our bodies have been equipped to survive most attacks from microbes.
I survived Chicken Pox, Measles, Whooping Cough, Mumps and Pneumonia as a child, as did all my siblings. The only one I recall was Whooping Cough and I remember that one because my baby sister was born when my other siblings and I were packed together in a space under the stairs to make room for the birthing in the bedroom.
Throughout my life I’ve had a few colds in the winter, but (as Trump says) I’ve never had the Flu or the vaccine. So my theory is that the world population will never stop pandemics until we develop “Herd Immunity”. The inside of our bodies are like the outside. You don’t develop muscles unless you exercise. You don’t develop immunity unless you survive a few antibodies. And yes, everyone doesn’t always survive and vaccines weaken immunity, just as couch potatoes don’t develop muscles.
End of sermon.
I meant develop antibodies. Sorry.
