a herd of buffalo can only move as fast as the slowest one. when the herd is hunted, the slowest and weakest buffaloes in the back of the herd are killed first. this natural selection is good for the herd, because the speed and health of the group improves by the death of its weakest members.
in much the same way, the human brain can only operate as fast as its slowest brain cells. as we know, an excesssive intake of alcohol kills brain cells, but it attacks the slowest and weakest brain cells first. in this way, a regular regimen of drinking beer eliminates the weaker brain cells. that makes the brain faster and more efficient.
and that is why you always feel smarter after a few beers.
