A glass of red wine a day isn't bad for your liver or your brain. In fact it is, as Lana said, good for your heart. So absolute teetotalism is just as damaging for your health as binge drinking.
Sadly, Allah didn't know that. How strange for a creator of the human race not to know how our biology works.
But then if Allah was the real creator of the universe (and according to his "rules"), he wouldn't have made a glass of red wine a day beneficial. He would simply have made
zero glasses more beneficial than 1 glass.
However, if I was god, I would have made 1 bottle a day beneficial. What is better for the world than happy people who live longer? Oops... apparently Allah prefers unhappy people who blow themselves up!
