A herd of buffalo can only move as fast as the slowest buffalo.And when the herd is hunted , it is the lowest and the weakest ones at the back that are killed first.This natural selection is good for the herd as a whole, because the general speed and health of the whole group keeps improving by the regular killings of the weakest members.In much the same way , the human brain can only operate as fast as the slowest brain cells. We know excessive intake of alcohol kills brain cells .But naturally, it attacks the slowest and weakest brain cells first. In this way, regular consumption of beer eliminates the weaker brain cells , making the brain a faster and more efficient machine and that is why we feel smarter after a few beers.
