Today, when I thumb through a magazine, I accidently bump into an interesting article which enumerate five unhealthy lifestyles which are enjoyed by our modern people. The author uses a vivid metophar in its title---Five methods  through which modern people are destroying themselves. I think the word "destroy" is quite precise for it shows the inevitably horrible result of modern lifestyles. How to change our unhealthy lifestyle is a problem we should not shirk.

 

The most acrimonious method: idling our brains. Simple calculations, such as add, minus, multiply and divide, are assigned to pocket calculator or embedded calculator of handset, a little more complex calculations are assigned to omnipotent computers. Our brains are not deign to do such trivial matters. Idling our brains, for mankind, is comfortable and happy. But its result is that our brains are taking the risk of drastical degeneration. In my own case, I find it is so, when I was in college, I could calculate some simple mathmatical problems, such as prices of commodities with discounts,  easily by heart. But now, if I meet such kind of problem, the first thing I think of is where my calculator is. Our brains are like an engine, if they are not used frequently, they will become duller than before.

 

The most effective method: idling your legs. During the evolvement, our ancenstors gained strong legs through using it frequently. But in modern society, we use plane and car to replace the function of legs and abandon a precious exercise--excursion. The liberation of legs bring about trublesome obesity which is the No.1 cause of heart deseases.

 

The easiest method: idling our intestine.The digestive system we inherit from our ancenstors should have been omnipotent system which could digest stone and pebble, like those of chicken and ducks. However, we begun to accustome to fine grain and our stomachs are becoming more fragile.

 

The most comfortable method: idling our sweat glands. Sweating should has been  a necessary physical reaction of  our body in hot environment. But modern city residents choose to eacape from hot wave by hiding into rooms with air-conditioning. As a result, our sweat glands lay off and the toxins culmulating in our bodies can't be taken out by sweat. Our normal metabolic function is disturbed thoroughly. A desease-prone body environment is gradually coming into being.

 

The fastest method: idling our immune system. In the past, for our ancenstor, catching cold did not mean having medicine at all. But now, having pills is a must-do. The direct result of idling our immune system is that we become slaves of medicine.
