Some religions outlaw everything adults tend to enjoy, such as gambling, rock and roll, dancing, alcohol, recreational drugs, profanity, pornography, oral sex, blasphemy, and in some extreme cases, the consumption of caffeinated beverages. In some strict Islamic societies, it is considered sinful for a man to look at a photograph of a woman in tight fitting clothes. What is left to live for at that point? Once these facts are considered, the existence of suicide bombers in such societies is hardly surprising.
