It's not often I can review a book and mention how it changes your brain, but that's apparently the effect of the colouring-in-for-adults phenomenon. There's a science behind it all that attests how alpha waves, a slightly more childlike, accepting, relaxed form of brain activity, are used by our bonces when we colour – and as opposed to the braver, thinking, active beta waves they're something the mind could do more of, especially in this kinetic, plugged-in, 24/7 lifestyle. So whereas I normally review books to help my readers make their mind up, here I'm mentioning this volume because it allegedly would change your mind.
