Comedian Richard Herring has a major problem. He's about to turn 40 and hasn't seen it coming. He's not married, doesn't have a proper job or 2.4 children.
But now, finally, it looks as if the world expects him to be a grown up - and he's completely unprepared for it. As the momentous and terrifying event approaches (his birthday), Richard notices a steep decline in his own behaviour.
Inexplicably he begins to behave more childishly - hanging out with 22-year-olds, developing an unhealthy addiction to Flumps and even getting into a ludicrous fight. How Not to Grow Up is the funny story of how a self-confessed perpetual Big Kid deals with his greatest fear - getting older - and is the perfect book for everyone who, deep down, still thinks that they're 18.
