Immunology 101: exposure builds immunity.
Continuous exposure in small doses is required for the body to develop resistance to New viruses
When the baby is born, it picks up "germs" from the mother's vaginal canal , a huge load of them which gives it a great start in life. C Section babies are less immune and they start with a handicap in life.
Children need to play in the mud, eat some mud, and get dirty, to develop their immunity
Everyone needs to drink the local water of the place they visit ( and not drmineralised, lifeless, germless "mineral" water) in order to pick up the local germs for the body to be familiar with.
We, all of us, life long, need to be always "exposed" to all that is out there so that our bodies are constantly facing these gems, and developing their responses to it, storing all of that in the cells' memories.
We are doing the opposite. We are isolating, masking, and rubbing our hands with alcohol. We are running away from germs .
I am not talking of corona. In the name of escaping from the corona virus, we are doing all that.
The prognosis is not good.
