A herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, it is the slowest and the weakest ones at the back that are killed first.
This natural selection is good for the herd as a whole because the average 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. Excessive intake of alcohol, we all know, kills brain cells, but naturally it attacks the slowest and weakest brain cells first.
In this way, regular consumption of wine eliminates the weaker brain cells, making the brain a faster and more efficient machine
