Is it true that you live to ninety-nine by walking after dinner?

In order to live a long life, we can say that we have tried our best, especially for the phrase "take a walk after dinner and live to be 99 years old", which many people think is right and has been circulated among the people. So can you really live to be 99 after walking around after dinner? In fact, after eating, it can promote blood circulation and help digestion and absorption of food, thus achieving the effect of prolonging life. However, this sentence is actually one-sided. Take a proper rest after meals, and then exercise properly to keep healthy. If we exercise immediately, it will make the blood flow to the limbs, reduce the digestive function, and also cause some harm, which will definitely increase the burden on the stomach and cause some stomachs. Although this sentence sounds a bit one-sided, walking after meals is really helpful to health, but for people of different ages, they should also consider their physical condition. Generally, middle-aged and elderly people should take a proper rest after eating, and then go for a slow walk on some flat roads. Although there is no complete scientific basis for this sentence, it has been proved that doing some appropriate exercise as much as possible after meals can keep you healthy. Therefore, it is not necessarily correct to walk after dinner and live to 99, but it is not completely wrong. Although you may not live to be 99 years old, you can certainly prolong your life, because proper exercise can promote blood circulation and body metabolism, which will strengthen our body's immunity and enhance the normal circulation of various systems. Therefore, it is definitely beneficial to take a walk after dinner, but we should judge this sentence according to our physical condition and living environment. It doesn't mean that in any case, taking a walk after meals will certainly achieve the effect of prolonging life, and sometimes even lead to some diseases.
