According to the recent study published in the journal Clinical and Experimental Research, epidemiological research suggests that moderate to high alcohol consumption is associated with a reduced overall mortality risk compared to non- and light drinkers.

Their study included over 1,800 people, aged 55 to 65 when the study began. Sixty-nine percent of the participants were men. The subjects were followed for 20 years.

Surprisingly, the group with the lowest mortality rate was moderate drinkers, who had one to three alcoholic drinks per day, followed by heavy drinkers, and then light drinkers, while non-drinkers had the highest mortality rate of them all.


Part of the theory as to why this is so has to do with the modern increase in methanol in food (and cigs), and the physiology by which ethanol helps us to process methanol. Methanol (wood alcohol) is a toxin. Mercola (the first source) offers a good rundown on a variety of possible factors, as well as some warranted warnings about the risks involved in alcohol consumption. Also it is worth noting here that the majority of study participants were male, and females have considerably more difficulty metabolizing ethanol.

I'm beginning to understand what I must do in order to understand a Brons lecture or powerpoint. If I don't already know the material, the lectures and powerpoints are nigh unintelligible to me. It is necessary for me to seek other sources. When I do, Lo and Behold! It's simple. It just seems insanely complex in the lecture.

I believe we're talking about NEUROtransmitters, here, but Brons is abstruse. Small molecule transmitters are fast acting in acute sensory and motor responses of nervous system. Both direct and indirect. Removed from synapse by diffusion, enzymes or reuptake. Drugs often work by affecting synthesis or removal of transmitters. The action of a neurotransmitter is determined by its receptors. One neurotransmitter may affect different types of receptors each with a different action.

Well I don't worry too much about grades so I didn't even check until today to see what I got. I got the A I expected, but the margin was closer than I expected! There were five of us in the class who got A's (no curve, 90% or better) and I slinked over the wire at 90.2%. That was close. But an A is an A is an A.
