I can safely say that the reason for a statistic like this is that in a violent country’s such as the Middle East, there isn’t much hope for a man over the age of 18 to live past his 30th birthday. They are at war all the time. It takes peacetime to age. They will always have this kind of turn around in there nations as long as they are at war. So far they have been at war since before the time of Christ, so I’m sure that these statistics will not change any time soon
