They are all pupils'. As long as you eat normally, you don't need special water. You can prepare water for him or give him some change. He doesn't have to drink. If you are thirsty and can't drink water, you will be in a hurry.

Man is a natural animal. After thousands of years of evolution, he wants to eat when he is hungry and drink when he is thirsty. If he lacks any elements, he will eat the unique flavor of that food and supplement it by eating more. This is a natural attribute. I'm not sick. Why do you drink so much water on purpose? Health can't go against the sky now. What about seven and eight glasses of water? If you are full, talk to an expert and he will tell you that your rice and soup are also in these seven glasses of water. If you are thirsty and drinking 7 glasses of water is not enough, ask an expert and he will tell you to drink more than 7 glasses of water a day. This kind of expert is funny, haha. .
