When my grandmother was 85 years old, her eyes were still sharp, and it was not a problem to thread a needle. Both ears are still sensitive and can detect subtle sounds. The teeth are intact and powerful, and the cauldron left by the firewood stove is actually chewed with relish. Speak with clear logic, loud voice and full of gas. Running around when walking, often traveling between villages, burning incense and worshipping Buddha, being a matchmaker for others!

The villagers around her said that she was in high spirits all day and didn't look like an 85-year-old man at all.

She has a habit of eating only two meals a day, and never taking a bite when she is full. Put down your chopsticks after eating a little greasy meat. After four o'clock in the afternoon, she stopped eating. Everything you bring out is delicious, and she will never taste anything.

What she said the most was: "If you want to be healthy, you must be hungry and cold." Occasionally, she would say, "When a person comes to this world, there is a certain amount of food to eat. After dinner, it's time for people to go. Those who eat and drink in the sea eat early and leave early. People who have a diet will live longer than those people. "

Today, I read the book The Revelation of Zeng Guofan by Professor Ceng Shiqiang, and saw a passage in the book:

This passage reminds me of my grandmother at once. She always adheres to the principle of "neither eating too well nor eating too full" in her diet. Could this be the reason why she is better than her peers? I really want to know the scientific truth contained in it!
