Today I passed by a newly opened traditional Chinese medicine health center

The sign reads "Ancient Method Health Preservation"
In ancient times, the average lifespan was only thirty or forty years, and even the royal family was no exception.
The mortality rate among princes and royal descendants was also very high, and the average lifespan was quite low.
Boss, are you using ancient methods for health preservation because you think modern people live too long?
But there are still people who believe that "ancient methods" are good. Is this intellectual deficiency?
