When I packed for this conference, I had a choice between my more ergonomic but geeky backpack or my more professional and less ergonomic laptop bag. I chose the laptop bag, a decision I have been regretting for a week.
I need to remind myself that I only have one back and that long term spinal health is more important than looking "professional," even at a UN conference. Not to mention that these conferences always produce lots and lots of paper, which you end up having to carry from place to place by the ream.
I woke up this morning with an aching back, which has only slightly diminished during the day.
Better to be a geek with a strong spine than a faux diplomat with a bad back.
