An extra hour for contemplation

The clocks changed last night, it happened whilst I was out, drinking with an Australian friend. I've yet to understand why we do it and I am sure I read it has something to do with a war or something, WW1 perhaps, usually these weird unexplained rules and procedures have something to do with a politician's decision in war-time and it stuck. I also learnt, whilst living in Spain, that Franco changed the time in Spain so Madrid would be in the same time-zone as his hero, Hitler, so politicians do weird things and when they make silly changes someone forgets to undo those changes and we are stuck with it, and the consequence of last night's clock change was an extra hour bed, or that is what should have happened but as I was out drinking and dancing until 3am and woke up at my normal time, the extra hour was wasted, I had 6 hours sleep and feel rough today as a consequence. I am using the "extra" hour that isn't to contemplate and digest my thoughts ...
