Will Life Expectancy be Shortened?
Since WWII, the life expectancy of human beings has risen substantially, which is attributed to the advances in health care, improved living standard, and peaceful situation. It is estimated that people will live longer than ever before in 2030. But not all of them have good luck, and we must clear that how long you live largely depends on your lifestyle. Smoking, staying up late, drinking, too much sitting and obesity are now responsible for reduced life expectancy and all diseases. We should focus on these bad behaviors. Smoking will life expectancy be shortened image 1 It is known to us all that a cigarette is the leading killer of both men and women, even our children. Some toxic substance produced by a cigarette not only is detrimental to smokers themselves but also non-smokers. You were passionate about your work and family, and you want to wander around the world with your lover, but now, as a heavy smoker, you cannot, because you will die from lung cancer. Or You led a healthy and happy life, but you will lose it as one of your family members is a heavy smoker and you will breathe in second-hand smoke. All of us are victims of smoking. Smoke will take at least 10 years off people’s life expectancy and they will eventually die from smoking-related diseases. A cigarette generally contains over 4,000 chemical compounds and at least 400 toxic substances (including carbon monoxide, acrolein, and other harmful substances). These harmful substances are bad for adults as well as our children. Children will more likely have blood vessels and heart diseases when their parents are smoking. It is reported that smokers who quit smoking between 24 and 34 years of ages will gain at least 10 years life compared to those who continue to smoke. Also, according to National Cancer Institute research, smokers tend to have 64% higher risk of death than those never smoke. Therefore, for our lives, our family and our children, we should stop smoking as fast as possible. If you are struggling to quit, you also try to use e-cigarettes (it is less harmful than e-cigarette and help smokers to stop smoking). Staying up late Will Life expectancy be shortened image 2 People often identified themselves as early birds and night owls, however, it seems that there are many night owls than early birds. Some people argue that night is a golden time during which they can do many things such as watch TV, have a conversation with friends and improve themselves. They may overlook a fact that evening-driven schedule will damage their health and even cut down their life expectancy. It is reported that each one hour that sleep is shifted, people have 11% more likely to have heart disease. In addition to this, if you often stay up later, you will suffer from so many diseases such as weight gain, heart disease. And Forbes says, “It’s the first study to show (if only in animals) that sleep loss can lead to irreversible brain cell damage.” It is clear that sleep is important for our lives and our life expectancy. Drinking Will Life expectancy be shortened image 3 Drinking good wine and taste good food is the most enjoyable things. Wine plays a big part in our daily lives. We drink a bottle of wine when feeling happy, and we also have a cup of wine when we get sad. Also, wine is still used to often entertain our guests. Modest wine is always so good for our health. But it is also noted that excessive wine consumption is exceptional, and it also kills many people. According to a research, each drink will cut 6.6 hours of life. If you drink too much, your life expectancy will drop dramatically as a result of cancer or the alcohol-related diseases. In addition to this, drinking and driving are a quite serious problem in recent years, and many people were injured and killed by drunk drivers. Never get drunk. Too much sitting  Will Life Expectancy be Shortened image 4 That sounds ridiculous but it is a truth. We often are fond of a sedentary job and hope that we can sit chained to our chairs all day. Once our work is complete, we always transition from desk to a car to a couch without doing daily exercise. It is now noted that too much sitting is linked to our life expectancy. Your lifespan will be shortened. American Cancer Society has conducted a test for 123, 216 people’s health effects for a 14-year period, and they eventually found that people who sit for 6 hours a day have a higher risk of death than those who sit less than 6 hours a day. So being a sedentary is associated with so many diseases, including heart attack, being overweight and dementia. In order to reduce the harm to your health, you must stand up and move around at regular intervals and do daily exercise. Overweight Will Life expectancy be shortened image 5 We have often know that overweight poses a high risk of death, and it is associated with many illnesses, including heart attack, stroke, kidney and liver cancer. Also,  being overweight is responsible for early death. But we still lead an unhealthy life and eat some junk food, and we finally get fatter. One important thing you now must understand that overweight will take 8 years off our lives and increase the risk of death. BMI is applied to calculate human’ weight and height, indicating people’ s health status. In general, if your body mass index of people (BMI) is 25 to 29.9, you are considered overweight, while a healthy weight is 18.5to 25. A research published in Lancet says that a slight increase weight will cause harm to our body. So losing weight must become a major task for very obese people. Having a good body and long life are everyone’s dream. So we should develop a good life so as to stay away from all disease.
