One day two men walked into the bar. Both men were exactly alike, a clone you could say. They both sat down for the bartender to fix them a drink. The first man sat down, waited on the bartender to fix his drink. When it was given to him he drunk it very fast, left, and had a happy life. The next man sat down, and waited on the bartender to fix his drink. When the drink was given to him he drunk it very slowly, and died right there on the spot. Why did the first man live but the second man die?
