ETERNAL LIFE (Part 21)

I continue excerpting Chapter 2 of SIMPLE SOLUTIONS for Humanity:


Germs

There is no scientific meaning for germs, which are single-celled and commonly thought of as bacteria. Also add archaea, only discovered in the ocean in 1977. Even if viruses are supposedly not alive, throw this group of microorganisms into the germ pot. There are single-cell fungi and protozoa, so they can be added, too.

These microscopic life forms appeared as long as 4 billion years ago, represented the only life for up to 2 billion years, and, actually, still rule Planet Earth, as it is reported that there is more mass in “germs” or micro-life than all the macro-life (humans, other animals, trees, whatever you can see that lives). There are studies showing that there is about the same amount of plant biomass as bacteria (about 2 billion tons each), but there is very roughly the same mass in archaea and viruses compared to bacteria, so germs still dominate. For the record there are 700 million tons of domesticated animals, 500 millions tons of krill (those small shrimp-like creatures eaten by whales and fish) and 250 million tons of us humans.

Every time you go swimming, consider that just in a liter of seawater live more than 20,000 different kinds of bacteria. Or everytime you kiss, don't think about the 40 million bacteria in a milliliter of saliva. There are about a billion different kinds of bacteria. If a virus had the shape of a baseball, a bacterium would be the circle around the pitcher’s mound and a human cell would be in the range of the ballpark. As a virus requires a host, it has to invade a microorganism, human or any life form, to survive.


Most of you don’t realize that:

o You harbor 100 trillion bacteria in and on you, but have only around 10 trillion cells of your own, thus, you host many times more germ cells than your own. Before you get too revolted, per above, your cell is much larger than a bacterium.

o You have probably up to four pounds of bacteria in your gut, and could have nine pounds total. Yes, this is most disgusting.

o Some of your personal cells have formed a symbiotic relationship with these germs, and, there are growing theories that they, in fact, now affect the nature of genes.

I've recently been writing about BOOP and MRSA, but, 99%+ of germs are good. While viruses exist only by attacking and nourishing themselves on living cells—thus, they are the natural predator for bacteria and you—there are no known pathogenic archaea. Some viruses, though, are used in gene therapy, so there is some good here. You will more and more see these beneficial germs in your diet. From baby food to yogurt, there are now more than 150 probiotic and prebiotic products in your supermarket.

The Dow Jones hit an 8-month high by jumping 188 to 9068. Ford was up to 7 for a while. Remember, I told you to buy when it was 1.9? Oil also increased to $67/barrel, but, I guess maybe the recession has bottomed, for gold fell $1/toz to $950.

There is some activity south and west of Hawaii, but no one seems concerned at this time.
