I am at the moment trying to complete a photography course, I have just learnt that the golden triangle is not a poppy growing area in Afghanistan, well, it might be but prior to that it was a mathematical equation, math was never a strong subject of mine, hence I struggle with this and my head hurts.... any shortcuts? Not to the whole head hurting thing, 2 bottles of Pinot Grigio, I am sure will sort that out and I am quite certain that I can do that on my own....
