I sometimes wonder whether I really am thick after all. There are moments when I try desperately to analyze just what I was thinking at a particularly stupid moment, and to the best of my memory, the answer is...nothing at all. Working on auto-drive is essential sometimes, no doubt, but only when the system really works. In my case, it seems to involve shutting down of not only self-awareness, but also thought (and the two, I think, can sometimes be disconnected).
