To be really obvious about something, if somebody straps an M1 on your shoulder and throws you in Iraq, you're going to get a sense of what the hell's going on there. Boy, you'll wake up fast when bullets are flying over your head.
Rules of living Don't worry, eat three square meals a day,say your prayers, be courteous to your creditors, keep your digestion good,steer clear of biliousness,exercise, go slow and go easy. May be there are other things that your special case requires to make you happy, but my friend, these, i reckon, will give you a good life.
