A few funny jokes, but the fourth old iron really pierced his heart.

I met a famous doctor recently. When chatting with him, he suggested to me: "In the future, we should exercise more, don't buy drinks, don't drink beer, don't drink red wine, drink more boiled water, don't drive when going out, take more buses or walk, don't eat out, try to be vegetarian and eat less meat, especially seafood!" I nodded and asked him, "What's wrong with me?" He said: "The income is too low!"
