Herbs and MrsS, just adding to the instructions to go to the GP. And Herbs, go with a full bladder as I'm pretty sure they will ask you to wee in a cup.
Snort at Beachy's "standard face" - that's really not the case, you know, but I know what you mean. I have an amazing ability to make no impression on people whatsoever - I have had people introduce themselves to me time and time again, thinking we haven't met. It's one of the reasons I dye my hair red - it's got better since I have been ginger. Dh was a bit sceptical when I first told him this (it has been going on my whole life, even as an admittedly quiet child) and then after a few years of seeing it happen time and time again, he admitted I must have some kind of cloaking device. He reckons I should have been a spy.
He, contrastingly, makes such an impression on people that we regularly have complete strangers coming up to him to say hi and remind him that they shared a spliff for 15 minutes on a beach in Thailand in 1991. 
I have exercised A LOT this week. Weights class on Monday, hour's cycle on both Tues and Thurs, and pilates this morning. At what point do I transform into Elle McPherson? What I do need to work on, I discover, is my posture - my shoulders are definitely starting to hunch forward and it's not a good look.
