Man cannot live on beer alone. Although in college my friend acquaintance Matt Gyzlowski lived on only beer for a week. The results were not encouraging. He was near delirious most of the week. I do not recommend trying to do this, but old Gyz did win a $500 bet. Either for survival or just because you are a typical overweight American glutton, you have to eat.
But that does not mean you have to stop drinking beer.
And that usually doesn’t mean you have to stop drinking really good beers.
