Two of the saddest words in the English language are "if only". I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.

    My father is famous in our family for saying, "Take the extra minute to do it right." I always try to live by the "extra minute" rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an "if only" moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.

    I don't only avoid those "if only" moments when it comes to safety. It's equally important to avoid "if only" in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say "I love you" or "I forgive you." When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn't be here. But then I thought about the fact that he's 84 years old and I realized that I shouldn't give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.

    I know there will still be occasions when I have to say "if only" about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I'm doing the right thing. I'm buying myself peace of mind and that's the best kind of insurance for my emotional well-being.

    Recently there has been a discussion on a website about “what would you miss most and least if you were stuck on a desert island?”

    Here are some of the answers:

Post 1

    Steve USA—Hi, everyone. What would you miss most and least if you were stuck on a desert island? For me, it would be the changing seasons in New England. I guess this will sound stupid but I'd probably miss the rain, too. I wouldn't miss getting up at six every day to go to work, though! What about you?

Post 2

    Tomas Germany—Good question. Steve, I think I'd miss different types of bread, and shopping at the supermarket. I'd miss the food most. What would I miss least? My mobile phone—I'd like to be completely quiet—at least for a little while.

Post 3

    Paola Italy—I would miss the company of people because I know I'd like to have someone to share experiences with. I'd go mad on my own. And I sure wouldn't miss junk mail—I hate coming home every evening and a pile of junk mail in my post box.

Post 4

    Miko Japan—Hi, I would miss Manga cartoon, the Internet and Japanese food, like sushi. I'd also miss TV shows and shopping for clothes… In fact, I'd miss everything.

Post 5

    Roger UK—I would miss my daily newspaper and listening to the news on TV and radio. I'd feel very cut off if I didn't know what was happening in the world. What I'd miss least would be traffic jams in the city, particularly my journey to work.

Post 6

    Jayne Russia—Why hasn't anyone mentioned their family? I'd be lost without my husband and two kids. They're the most important for me. And I can't get started in the morning without a cup of black coffee. I wouldn't miss doing the housework!

Post 7

    Jaime Mexico—It would have to be music. I couldn't live without my music. I wouldn't miss going to school at all or doing homework!

    If you go into the forest with friends, stay with them. If you don't, you may get lost. If you get lost, this is what you should do. Sit down and stay where you are. Don't try to find your friends—let them find you. You can help them find you by staying in one place. There is another way to help your friends or other people to find you. You can shout or whistle(吹口哨) three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help.

    Keep up shouting or whistling. Always three times together. When people hear you, they will know that you are not just making a noise for fun. They will let you know that they have heard your signal. They will give you two shouts or two whistles. When a signal is given twice, it is an answer to a call for help.

    If you don't think that you will get help before night comes, try to make a little house with branches(树枝). Make yourself a bed with leaves and grass.

    When you need some water, you have to leave your little branch house to look for it. Don't just walk away. Pick off small branches and drop them as you walk in order to go back again easily. When you are lost, the most important thing to do is to stay in one place.

Londoners are great readers. They buy vast numbers of newspapers and magazines and of books — especially paperbacks, which are still comparatively cheap in spite of ever-increasing rises in the costs of printing. They still continue to buy "proper" books, too, printed on good paper and bound（装订）between hard covers.

    There are many streets in London containing shops which specialize in book-selling. Perhaps the best known of these is Charring Cross Road in the very heart of London. Here bookshops of all sorts and sizes are to be found, from the celebrated one which boasts of being "the biggest bookshop in the world" to the tiny, dusty little places which seem to have been left over from Dickens' time. Some of these shops stock, or will obtain, any kind of book, but many of them specialize in second-hand books, in art books, in foreign books, in books on philosophy, politics or any other of the countless subjects about which books may be written. One shop in this area specializes only in books about ballet!

    Although it may be the most convenient place for Londoners to buy books, Charring Cross Road is not the cheapest. For the really cheap second-hand books, the collector must venture off the beaten track, to Farringdon Road, for example, in the East Central district of London. Here there is nothing so impressive as bookshops. The booksellers come along each morning and pour out their sacks of books onto small hand carts. And the collectors, some professionals and some amateurs, have been waiting for them. In places like this they can still, occasionally, pick up for a few pence an old one that may be worth many pounds.

    If you like texting and are trying to lose weight, a new study found that using texting to track(追踪) diet and exercise habits may help you lose weight.

    Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are trying to lose weight. Using a computer or a pen and paper to record information, however, can be a burden and cause some people to give up.

    Duke University researchers said using text messages to track eating and exercise habits can save time, and increase the chances that people will stick with their weight-loss rules.

    The study included 26 obese women with an average age of 38. The women used daily texting as part of their weight-loss program. The text messages focused on tracking personalized goals, such as avoiding sugary drinks or walking 10,000 steps a day. Messages also provided brief feedback (回复) and tips.

    Every morning, the women received a text from an automated(自动的)system that said, "Please text yesterday's personal information of steps you walked and how many sugary drinks you had." Based on the women's responses to the text message, the system sent another text with personalized feedback and tips.

    After six months, the women who used daily texting lost an average of nearly 3 pounds, while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds, according to the study, which was published in the Journal of Medical Internet Research.

    "Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior," Dori Steinberg, who was responsible for this research, said.

    Steinberg said, "Text messaging offers several advantages compared to other self-monitoring methods. Unlike web-based diet and exercise diaries, data in a text message can be entered quickly on nearly all cellphone platforms so it is very convenient to receive feedback. Besides, because of the limited number of words used in text messages, it saves time."

    Why we cry with happiness show: Responding with a negative reaction helps us deal with extreme joy. If you cry with happiness at weddings, you are responding to a happy experience with a negative reaction. The researchers believe the unusual reaction may help renew emotional balance in us and keep extreme emotions under control. The findings make it clear how people express and control their emotions, which could help improve their understanding of people's mental(精神的) health.

    Dr Oriana Aragon set out to explore the phrase “tears of joy”, which she said never made sense to her. But after studying a series of incongruous(不和谐的) expressions, she now understands better why people cry when they are happy. “People may be renewing emotional balance with these expressions,” she explained. “They seem to take place when people are struck by strong positive emotions. People, who do this, seem to recover better from those strong emotions.”

    The report show various examples of responding to a positive experience with a negative emotion, such as, a crying wife seeing the husband returning from war again, and teenage girls screaming at a Justin Bieber concert. Examples also include a baseball player who hits a home run, only to be slapped(拍) on the back by teammates, as well as when people cannot help kissing babies' faces who they consider lovely.

    Dr Aragon and her team discovered that people, who expressed negative reactions to positive news, were able to moderate(缓和) strong emotions more quickly. There is also some evidence that strong negative feelings may provoke positive expressions. For example, nervous laughter often happens when people are faced with a hard situation. We've seen people smiling during times of extreme sadness.

    “The findings affect our knowledge of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together,” Dr Aragon said.
