I have been at ease for a long time, so I want to think about it for a long time. There is no difference between keeping in health in the past and keeping in health now. When you say that many people are keeping in good health now, you are just talking about a profession. This just shows that many people want to live longer now, but they don't want to spend time on diet or exercise. They want to take a shortcut as a business, usually through health care products or something, but it is of no practical use.
