A heard 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 heard as
a whole, because the general speed and health
of the whole group keeps improving by the regular
attrition 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 beer eliminates
the weaker brain cells, making the brain a faster
and more efficient machine.............
