There is certainly something more for people to maintain health, which is the way we think about health. The emerging of knowledge of modern medical subjects actually create a concept of maintaining health. It basically marks the line to tell apart what is unhealthy and what is okay. Take the States an example. During the entire 60s and 70s of the last century, smoking was highly discouraged. When the pictures showing rotted lungs and digestive system were published, it, of course, disgusted and shocked the mass. This movement was almost a huge medical lesson to teach the nation how cancer functions. The awareness of the importance of maintaining health were being rooted into all aspects of American life ever since. It is the fact that people WILL do things for their own sake instead of being forced to give up those "fantastic chemicals" such as nicotine and alcohol.
Alongside the improvement of a materialistic condition and the mentality of daily-based healthcare. It certainly is much easier for modern men to maintain healthy than any moment in human history.
