"Health Master" taught others to keep in good health, but he died, 5 1! What is the reason?

This is hard to say. We have seen TV news that many health care masters do this program to make money, instead of really seeking benefits for others and teaching people some health care methods. Therefore, it is very likely that he learned these things from books instead of doing so. On the other hand, people like this make a lot of money through the above-mentioned methods, and naturally it is unlikely that they will live a comfortable life in the future.
