My mother used to warn me against drinking: "It blunts the mind and brutalizes". To keep one's mind sharp and alert was her lifelong goal, she succeeded for herself, not so for me. As I am getting older so is lessening my tolerance for alcohol. In the end, I'm near the point that I'll make kiddush with grape -פרי הגפן lattu sensu.
My instinct says that mixed-race factories cannot be efficient and mixed-race armies cannot win battles. Yet, reality shows that to be untrue. The future may look like that famous cantina scene in Star Wars.
