"At first glance the punk diet not only satisfies a consumer's desires but also protects their health. It's a perfect choice. Those who have eaten these so-called punk health foods should know that most products that take the punk route have no punk taste at all, and staying healthy is also a whim－but healthcare is a good business."

Taking action is the essence of staying health, Jiang says.

"It's easier for young people to look after their health than is the case with older people. As long as good living habits are maintained that's OK."

Jiang then spells out what some of those habits are.

"Go to bed early. This is the most important thing. The main reason why many young people are in poor health is that they often stay up late. It's incredibly important to maintain good sleeping habits, and to try to get sleep and rest before 10:30 or 11 pm."

Playing on your mobile phone at night is likely to deprive you of quality sleep, studies have found. A survey by the market consultancy iResearch found that nearly 80 percent of those who went to bed late said that playing on mobile phones is what they like doing before bedtime. Nearly 60 percent said that it was playing with their mobile phones that got them into the habit of staying up late. Among those who play with mobile phones before going to bed, as many as 62.7 percent say they sleep poorly, according to research.

A survey by Shandong Talent of 50,000 post-1990 white-collar workers in Shandong province found that being single or not having a job or enough money was not the biggest anxiety of this group, but of being seen as "fat and middle-aged".

There is little doubt that female white-collar workers pay more attention to health preservation, says the report. The two sexes have different priorities, with men paying more attention to improving their physical fitness and women paying more attention to their physical appearance.

As for what people think of healthy living, a survey by Zhiwei Data found that among 1,000 respondents 41.3 percent said drinking good herbal tea was the most important thing for them in staying healthy, followed by 40.3 percent who said maintaining a healthy lifestyle was the most important thing, and 7.6 percent who said what was most important was using traditional Chinese medicine. Only 2 percent rated a regular fitness program as most important. This suggests that young people adhere to the belief that you should budge only if you really need to.

"The two cheapest and cost-effective ways of staying healthy are getting exercise and going to bed early," Jiang says. "They are much more affordable than eating various health products and applying various cosmetics. If you stay up all night, even the cosmetics of royalty can't solve your problem skin, and the very best doctors can't cure your physical problems.

"Do something to improve your quality of life and make yourself happy at heart. It's more of an attitude. The awe of life and self-esteem are the things that really matter most."
