Four common bad habits combined — smoking, drinking too much, inactivity and poor diet — can age you by 12 years, sobering new research suggests.

一项最新研究结果让人警醒：吸烟、酗酒、缺乏运动和饮食不合理这四个不良习惯会让你看上去老12岁。

The risky behaviors were: smoking tobacco; downing more than three alcoholic drinks per day for men and more than two daily for women; getting less than two hours of physical activity per week; and eating fruits and vegetables fewer than three times daily.

这些高风险行为包括：抽烟、男性每天喝酒超过三杯或女性每天喝酒超过两杯、每周运动不足两小时以及每天吃水果和蔬菜少于三次。

The findings are from a study that tracked nearly 5,000 British adults for 20 years, and they highlight yet another reason to adopt a healthier lifestyle.

这些发现来源于对近5000名英国成年人展开的一项长达20年的跟踪调查，调查结果进一步强调了健康生活方式的重要性。

Overall, 314 people studied had all four unhealthy behaviors. Among them, 91 died during the study, or 29 percent. Among the 387 healthiest people with none of the four habits, only 32 died, or about 8 percent.

总体来看，受访者中有314人占尽四种不良习惯。其中有91人在研究期间去世。而在387位四种坏习惯都没有的最健康人士中，只有32人在此期间去世，比例仅约为8%。
