We have become so fastidious clean, and sanitay that our immune system never gets a workout. Now every little bug make us deathly sick.
I eat boiled eggs unrefrigerated for days.
I eat summer sausage years past its expiration date, as with many foods, canned and not.
If the meat smells off, I eat it anyway.
I make colonial style pickles by fermentation.
I make Sauerkraut the old country way.
Work your immune system or you will catch a stomach bug and die.
I worked around inmates in dorms full of viruses of all kinds including Corona and swine flu.
Never a sniffle.
