As we all know, a herd of Buffalo can only move as fast as the slowest member. When the herd is hunted, it is the slowest and weakest ones at the back which are killed first. This natural selection process is good for the herd as a whole as the general speed and health of the group keeps improving by the regular killing of the weakest members. In much the same way, the human brain can only operate as fast as the slowest brain cells. Now, as we know, excessive intake of alcohol kills brain cells. 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. That is why you always feel smarter after a few beers!! Going out to test this theory tonight!
