Something to consider....

A herd of buffalo can move only as fast as the slowest buffalo, and
when the herd is hunted, it is the slowest and 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 culling 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
off 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, constantly making the brain a faster and more efficient
machine. So drink more beer!
