Bite-size guide to happiness

IF the thought of ploughing through a weighty self-help tome fills you with dread, help is at hand. I Want to Be happy (£7.99, hardiegrant.co.uk) is a handbag-sized book with chapters short enough to be read during a tea break. Written by journalist harriet Griffey, it covers everything from the science behind contentment and what can be done to trigger our ‘feelgood’ hormones such as serotonin, to what to eat to be happy.
