The best way to help our immune systems: teach them to recognize intruders, via vaccination
I'm rereading Carl Sagan's book "The Demon-Haunted World" and came across the following which I believe is relevant to Gina and others worried about the devil that is science.
Human life span:
Pre-History to medieval times: 20 to 30 years
1870s: 40 years.
1915: 50 years.
1930: 60 years.
1955: 70 years.
2000+: 80+ years.
What is the cause of this stunning, unprecedented, humanitarian transition? Sagan says, "germ theory of disease, public health measures, medicines and medical technology. Longevity is perhaps the best single measure of the physical quality of life. This is a precious offering from science to humanity-nothing less than the gift of life."
He goes on to discuss microorganisms mutating and human countermeasures and "penetrating progressively more deeply toward an understanding of the nature of life--basic research."
this chart is from mid 2021, before Delta and Omicron, so the information on boosters needs updating
almost everything requires repetition. Even the most delicious meal doesn't nourish someone forever.
Seriously, most medical treatments, whether high tech or low tech, don't work with only one dose.
