My aunt has been doing direct sales of health wine, selling a lot and losing a lot, but she still firmly believes that she can earn money back. Once a customer came to ask for compensation, and she didn't care. My mother said to persuade her, and then I told her that wine has no health care function since ancient times. The main component of wine is ethanol, which is completely unnecessary for human body. After drinking it, it was completely metabolized by the liver. In the process of liver metabolism, a series of harmful substances such as acetaldehyde, reactive oxygen species and free radicals will be produced. Drinking alcohol, not only has no health care function, but is harmful to health. Although it didn't stop at first, it couldn't compare with the whispering in my ear every day.
