First of all, the background is different. Today's young people have something that people didn't have in previous times: they are in an era of peace and rapid technological development. In this peaceful era, we have a living environment that can develop freely and get more and better choices; Peace gives time for the development of science and technology, thus promoting the development of science and technology, especially civil science and technology, making it easier for people to obtain information and live more conveniently.

Therefore, young people focus on pursuing a better and higher quality of life, and pursuing a high quality of life means having health.

Secondly, the improvement of education level. With the popularization of the nine-year compulsory education system, the convenience of acquiring cultural and educational knowledge, and people's emphasis on learning and education, more and more people can receive good cultural education, so young people's cognition of life has changed and improved.

Then there is the change of young people's views on health care. Health can't be acquired overnight. Health is invisible and intangible, and it is a personal project that needs long-term investment. Naturally, young people begin to exercise and maintain themselves through various channels to make themselves healthy and have more possibilities.
