Ah, that's easy: absolutely NONE of it will be directly useful in your day to day work (unless your day to day work is very unusual indeed). It will be instructive, it will be amusing, it may even be illuminating...but it will almost certainly NOT be useful. And I certainly wouldn't blame you if you feel that isn't worth traveling all the way in to London for. Damian
