This week has been exceptionally busy. Luckily the schedule this evening includes an few hours at the spa in Bath. I have learnt some things though. On Monday I learnt that watching two A list celebrities on stage makes the audience slightly over excited and that a high proportion of ladies I know have a soft spot for Jeff Goldblum. On Tuesday I learnt about cooling and boreholes and waste heat and ventilation shafts. On Wednesday I learnt that beautiful music in beautiful rooms can move you to tears. On Thursday I learnt that learning three nights in a row makes me tired on a Thursday.
