              Four common bad habits combined—smoking, drinking too much, inactivity and poor diet—can age you by 12 years, sobering new research suggests.
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.
Overall, 300 people studied had all four unhealthy behaviors. Among them, 90 died during the study, or 30 percent. Among the 400 healthiest people with none of the four habits, 8 percent of them died.
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.
These habits combined substantially increased the risk of death and made people who engaged in them seem 12 years older than people in the healthiest group, said lead researcher Elisabeth Kvaavik of the University of Oslo.
The healthiest group included never-smokers and those who had quit; teetotalers, women who had fewer than two drinks daily and men who had fewer than three; those who got at least two hours of physical activity weekly; and those who ate fruits and vegetables at least three times daily.
"You don't need to be extreme" to be in the healthy category, Kvaavik said. "These behaviors add up, so together it's quite good. It should be possible for most people to manage to do it."
The US government generally recommends at least 4 cups of fruits or vegetables daily for adults, depending on age and activity level, and about 2 hours of exercise weekly.

When people want to know about the weather,they usually go to their radios,TVs, newspapers,or to the Internet.However,you can also find many weather signs among wildlife, because of their highly developed senses.Drops in air pressure(压力) produce an effect on small animals in many ways.Mice and deer are good weather indicators.People who spend a lot of time outdoors have observed that,before a storm,field mice come out of their holes and run around.Deer leave high ground and come down from the mountains.
Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways.For example,some birds become irritable(急躁的) and quarrelsome and will fight over a piece of bread.Other birds chirp(叽叽喳喳) and sing just before a storm.It seems they know they won’t get another chance for an hour or two.Birds also seek safe places before a storm.You will sometimes see birds settling in trees or gathering together on a wire close to a building.Pre-storm low pressure makes the air so thin that birds have difficulty flying.
It is unusual to see many birds flying overhead in the summertime,rather than during the periods in the spring or autumn.Watch for other weather signs if you see this.If they fly in the wrong direction,they may be flying ahead of a storm.
By paying closer attention to some important signs in nature,we can become better prepared for any kind of weather.
