What is the real reason that Bush continues to stay in Iraq? He stated that he wouldn't leave Iraq until he has "won" the war. Does anybody still think his only true reason to stay in Iraq is for the oil, because he did state sometime in November last year that oil was one of the reasons to stay, that the enemy would use oil-blackmailing against the US? Any opinions?

My baby is 15 weeks old and I have noticed her watching me alot when I am eating. She always seems to be hungry so I got her some Farex (baby rice cereal) and she absolutely loves it. I know it says on the box that it isn't recommended for babies under 4 months but do you think a couple of weeks early will matter?

I mastered maths entirely by myself. There is no point in attending those classes since I can read those textbooks, try out problems and check for the answers until I get it right. I actually became smarter than all my teachers at the end of each course at solving problems.
Was it just my strong inclination towards mathematics, or is it the same for everyone?

got so bad I literally had to let my arm lay limp for almost two weeks. If I accidentally moved it (as a normal reaction to grab something, etc) it hurt so bad I would yell involuntarily, lol. It's not funny actually cause it hurt so bad even when I wasnt moving it that I almost started crying and I dont cry because of pain. So anyways, it went away and I wrote it off to sleeping on it wrong or something. But then two weeks after that arm healed my other one did the EXACT same thing. Really strange. What could this be? Just bad luck to sleep on both shoulders wrong in the same month?

My photography can be seen at www.patkgallery.com. I own the rights to these photos and have model releases for all of these photos.

Be honest, do you think these images will sell? If so, where would be the best place to sell them.
