In order to live a longer life, what should people do? [originaltext]M: Hey! Jen

M: Hey! Jenny, do you want to live a longer life?
F: Why? Of course! Everyone hopes so.
M: Look, here is some advice given by experts on how to live a longer and happier life.
F: They must tell people to do exercise and keep a healthy diet.
M: Yes. They say 30 minutes of mild exercise a day will increase your life span. You can do things like walking, gardening or taking exercise classes.
F: And we should eat a balanced diet with low calories, cut back on red meat, sugar, coffee, alcohol and salt, eat more fruit, grains and vegetables.
M: Why? Jenny, you’ve read this article?
F: Not at all. But everyone knows that.
M: Come on! I think there is some valuable advice. For example, they say you should enjoy people more, join some social clubs or groups so that you share your life’s joys and sorrows with them and fight depression and stress.
F: That makes sense. In this way, we can have more positive attitudes towards life and stay optimistic because we feel we’re not alone. What else does the article say?
M: You should stay mentally active. Because the decline of our brain power will shorten our lives, too. So read the newspaper, visit the public library, balance your checkbook without using a calculator, do crossword puzzles and so on.
F: I think this advice is for old people.
M: Not necessarily. Because it also persuades young people like us to do regular checkups and prevent illness like cancer, high blood pressure which threaten our longevity.
F: All right, I don’t mean to argue with you. Are you going to follow every piece of advice listed there?
M: Well, they may be good advice, but you know, chocolate is my favorite.
