ABSTRACT
The time is around 7 am; George, 57, is getting out of bed and thinking about the day ahead-and the evening’s night drive. In the morning he makes sure that the children get to school, does the shopping, and cuts the lawn. In the afternoon he tries to take a nap. He gets just half-an-hour’s sleep before it is time to drive to the haulage contractors at 5 pm. He collects his brand-new 25 m-long truck with its 620 hp V8 diesel engine, which conforms to the EU’s new exhaust gas directive, and drives to the freight terminal. Then he begins a couple of hours work, loading the truck and doing paperwork. At 8.15 pm he sets off. There is only moderate traf—c and driving is easy. Towards midnight, darkness and mild fatigue creep over him and it is time for a break. He has a late dinner at a roadhouse, drinks coffee, buys a couple of bottles of Coca Cola, and continues on his way. For a while he thinks about his eating habits, his weight problem, and the company doctor’s warning about the risk of diabetes-his blood values are not ideal. What to do?
