A great gift book for possibly the most impossible person to buy for! The Book of Thunks will shake up your templates, rattle your thought routines and force you to think about things differently. A Thunk is a beguiling question about everyday things that stops you in your tracks and helps you start to look at the world in a whole new light. So find a friend or family member, ask a Thunk, disagree with their answer (remember there are no right and wrong answers) and keep your brain working longer and better. If you typed the word run a thousand times would that be a short story? Warning: A few of these Thunks are unsuitable for use with children.
