One thing that women often claim about high-heels is that they are 'impossible' to walk in. Well, men in China have been proving that's not quite the case, by taking part in a series of sprinting events wearing high heels - see.
A fantastic idea - take unusual or awkward clothing and see how fast you can run in it. The sack race only takes place at school and you never see it after that - but why? It's a fantastic race, testing a multitude of skills, mainly jumping, but also balance and, er, speed.
The egg and spoon race - another great race. Why do we do it? When else in life do you need that skills? Do children have an inherent love of running with delicate food? Odd world.
