Two Interesting Facts

1. Did you ever wonder how bacteria such as E. coli get into human digestive systems in the first place? Apparently, they enter the digestive tract after birth, through the mouth and the anus. You can read about it here.

2. In 1969, a teenage boy in St. Louis died of a mysterious illness. His doctors, though baffled, had the foresight to save blood and tissue samples. Nearly two decades later, these samples tested positive for the presence of HIV. You can read about it here. This is widely regarded as the first known American death due to AIDS. The strain of HIV turned out to be different from the strain involved in the current epidemic. You can read about that here, in the last few paragraphs.

Here "down on the farm," we know that Momma Cow must lick the newborn calf all over, because one of the things she is doing is transferring a whole bunch of different kinds of bugs to her calf. One REAL important one is the bacteria that helps cows break down grass (cellulose) into digestible sugars. If a calf is rejected at birth, it's doomed. There's gotta be some kind of cool moral to all this.

Ugh. I have been thinking about this since I first read it yesterday morning. Disturbing stuff girl. Although, disturbing in one of those fascinating ways that makes you look up everything else about it.

You are making me nervous, Arabella. In the 1960's, I was operating under the assumption that you couldn't catch anything you couldn't get rid of. Not from 'close association', anyhow.
