Is it really that big to live at the end of sixty-six?

In ancient China, because of the backward conditions in all aspects, people didn't have enough to eat, not to mention nutrition, not to mention medical conditions and facilities, so people at that time were 66 years old, which was considered as a long life. But in today's society, because the material conditions are very rich, everyone eats even more nutrition. Well, the medical conditions and equipment are very advanced, so there are many people who live to 8 years old, and there are many people who live to over 9 years old. Therefore, in today's society, 66 years old is not a high life. < P > In ancient China, because of the backward conditions in all aspects, people did not have enough to eat, let alone eat.
