Cliff was right!
Cliff's theory of the survival of the fittest brain cells now seems to be proven. The theory ran that alcohol kills brain cells, but of course it kills off the weak and unhealthy brain cells first (much as happens with grazing animals on the plains of Africa). This leaves just the fit, healthy and active brain cells left to run all your systems. Obviously the overconsumption of alcohol kills off more than just the weak cells and so gets the good ones which you need. This is also born out by this new study.
