Japanese Car Keeps Watch for Drunk Drivers A concept car developed by Japanese company Nissan has a breathalyzer-like detection system and other instruments that could help keep drunk or over tired drivers off the road. The car’s sensors check odors inside the car and monitor a driver’s sweat for traces of alcohol. An in-car computer system can issue an alert or even lock up the ignition system if the driver seems over-the-limit. The air odor sensors are fixed firmly and deeply in the driver and passenger seats, while a detector in the gear-shift knob measures perspiration from the driver’s palm. Other carmakers have developed similar detection systems. For example, Sweden’s Volvo has developed a breathalyzer attached to a car’s seat belt that drivers must blow into before the engine will start. Nissan’s new concept vehicle also includes a dashboard-mounted camera that tracks a drivers alertness by monitoring their eyes. It will sound an alarm and issue a spoken warning in Japanese or English if it judges that the driver needs to pull over and rest. The car technology is still in development, but general manager Kazuhiro Doi says the combination of different detection systems should improve the overall effectiveness of the technology. "For example, if the gear-shift sensor was bypassed by a passenger using it instead of the driver, the facial recognition system would still be used," Doi says. Nissan has no specific timetable for marketing the system, but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015. The car’s seat belt can also tighten if drowsiness is detected, while an external camera checks that the car is keeping to its lane properly. However, Doi admits that some of the technology, such as the alcohol odor sensor, should be improved. "If you drink one beer, it’s going to register, so we need to study what’s the appropriate level for the system to activate," he says. In the UK, some research groups are using similar advanced techniques to understand driver behavior and the effectiveness of different road designs. Which of the following is NOT mentioned in Paragraph 6

An external camera checks that the car is going properly.
B. The car will automatically keep to its lane.
C. The seat belt will tighten when the driver is found drowsy.
D. The technology of the alcohol odor sensor should be improved

Retirement Brings Most a Big Health Boost The self-reported health of the newly retired improves so much that most feel eight years younger, a new European study suggests. This happy news was true of almost everyone except a small minority only 2 percent who had experienced "ideal" conditions in their working life, anyway. "The results really say three things: that work puts an extra burden on the health of older workers, that the effects of this extra burden are largely relieved by retirement and, finally, that both the extra burden and the relief are larger when working conditions are poor," said Hugo Westerlund, lead author of a study published online Nov. 9 in The Lancet. "This indicates that there is a need to provide opportunities for older workers to decrease the demands in their work out of concern of their health and well-being. " But of course, added Westerlund, who is head of epidemiology at the Stress Research Institute at Stockholm University in Sweden "not all older workers suffer from poor perceived health. Many are indeed remarkably healthy and fit for work. But sooner or later, everyone has to slow down because of old age catching up. " Last week, the same group of researchers reported that workers slept better after retirement than before. "Sleep improves at retirement, which suggests that sleeping could be a mediator between work and perception of poor health, "Westerlund said. This study looked at what the same 15,000 French workers, most of them men, had to say about their own health up to seven years pro-retirement and up to seven years post-retirement. As participants got closer to retirement age, their perception of their own health declined, but went up again during the first year of retirement. Those who reported being in poorer health declined from 19.2 percent in the year prior to retirement to 14.3 percent by the end of the first year after retiring. According to the researchers, that means post-retirement levels of poor health fell to levels last seen eight years previously. The changes were seen in both men and women, across different occupations, and lasted through the first seven years of not punching the clock. Workers who felt worse before retirement and had lower working conditions reported greater improvements as soon as they retired, the team found. The study analyzed the participants’ perception of their own health in a certain period.
