I spent yesterday evening in an old factory building off Brick Lane playing kids' games with an organisation called Fun Fed. The idea is that a bunch of adults get together and act like children for a couple of hours. We played tag and stuck big coloured discs on ourselves so that we could become human Twister mats.
There was an awful lot of running around and I was thinking that I ought to get to aikido a bit more often. Being a child is very hard work.
