I did something today that I don't normally do.
My job is predominantly reactionary requiring fast response times so the tendancy is to get stuck in situ. If I leave the building it's only ever to grab a sandwich which I'll then eat at my desk.
So, today I went out for a walk. It wasn't very interesting, just a trip round the block and was only for 20 minutes, but there was no reason for it. It was a walk purely for the sake of walking.
Something I need to do far more often.
