What's considered investing for us as a person? Perhaps some would say it is dignity, but actually nothing can be compared with health. Our body is the most important investment in our life, regardless of whether you are elderly, middle-aged or young. The key is not to go overboard in anything. Whether you are worried if you will get sick, or you couldn't care less if you get sick, there is a problem in both cases. For example, it is definitely not good if you are overweight, but it will cause othere problems if you are too fixated on staying thin. No matter what you do, you must realize that we shouldn't do too much or too little in anything. .
