Re Alcohol by Veitch (2003)
I was inspired by the following (not exactly this form of words, I was sent something similar several years ago, but I can’t locate it immediately).
A herd of bisons moves only so fast as the slowest animal in it. When predators attack the herd they capture and kill the slowest bison at the end of the herd. Such natural selection is only good for the herd because it keeps the animals in good health, and the herd also becomes faster. A similar process takes place in the human brain. The brain can function only as fast as its slowest cell. As we all know, an excess of liquor destroys brain cells, yet due to the above-described natural selection alcohol destroys the slowest and the weakest cells first. Regular beer drinking therefore destroys slow brain cells and makes the brain faster and more efficient.
