the first real run of my study is next week, which means of course that it's time for everything imaginable to go wrong. the most amusing mishap, i think, was the magnetic strip on the scanner room door breaking, meaning that it swings open and refuses to stay shut. doorstops won't work -- no gap between seal and floor -- so we have resorted to propping sandbags up against the outside to keep it closed, and, when those don't work, leaning against it when the scans begin. it's all very apollo 13, except without the danger of dying horribly in space.
