You need to know your stress levels before you book a holiday. This quiz for evaluating stress originally surfaced in a Macmillan medical book in 1982 but in various forms it has been around for much longer. Basically what you need to know is whether you have been under too much stress in the past six months. If you have then it may affect your choice of holiday, your means of travel. • Going through an airport is a high stress situation. • Charging around the countryside on an explorer expedit.
