How potent is stomach acid? If it’s really acidic, why doesn’t it burn through your stomach and intestines? And why doesn’t it burn, say, the floor, if you throw up? What CAN stomach acid burn through? Can it be compared with any other acid? How is it produced?

We all have a broad range of emotions. Am I correct in believing that each emotion has an evolutionary significance? If so is each of our emotions controlled by chemicals in the brain?
