For decades, experts have been puzzled by what causes many previously happy, carefree young men to become perpetual moaners as soon as they hit middle age. And now they have found it, uncovered the truth behind the Holy Grail of modern medicine: the grumpy gene.

To discover whether you (or your loved ones) possess the grumpy gene, this quiz book has been devised to gauge your reaction to hundreds of different situations, from airport scanning machines that never work to parcel delivery men who choose to ignore the address clearly marked on the label and prefer to drop off your parcel at any random house in the vicinity.

Points are awarded for each answer and your total score indicates where you rate on the grumpy scale.
