But if I asked you to write me a list of instructions that would teach me how to ride a bike, as my four-year-old son did when we bought him a bike for his last birthday, you would really struggle to do that.
Men om jag bad dig skriva ner instruktioner som lär mig att cykla, som min fyraåring gjorde när han fick en cykel på sin födelsedag, så skulle du få kämpa.
