You may have read this one before. It is a superbly put argument creative enough for you to wonder, just for a moment, that perhaps there is some truth in it.
A herd of buffalo is said to move as fast as the slowest buffalo. And when they are hunted, it is the slowest and the weakest that are killed first. This natural "trimming" infact benefits the herd, as the slower members gets eliminated, the overall speed of the herd increase.
In much the same way, the human brain can operate only as fast as the slowest brain cells through which the electrical signals pass.
It is also known that excessive intake of alcohol kills off brain cells, it attacks the slowest and weakest brain cells first. Therefore, regular consumption of spirits helps eliminate the weaker brain cells, constantly making the brain a faster and more efficient.
I can't think of any better reason for having a cold one tonight. Let's see if my posts get smarter from tomorrow.
