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.

    I can't think of a better way of appreciating a new culture than by taking part in one of its festivals. You'll find that some festivals are celebrated by an entire country, while others may be known only to a single city or region, but either way festivals play an important role in a certain culture. Just enjoy them!

★ Tomatina — Bunol, Spain

    Every last Wednesday in August, the town of Bunol is filled with tons of tomatoes in the world's biggest food flight. Many people wear goggles (护目镜) during this hour of great fun, as the town becomes a red river.

★ Boryeong Mud Festival — Boryeong, South Korea

    For two weeks in July, millions gather in Boryeong to experience the grey pools and slides. What began as a way to help sell the region's mineral-rich mud has turned into a festive party with music and fireworks. The mud is usually only available in cosmetic products (化妆品), but here you can cake yourself in grey as you want.

★ Holi — India

    Holi, the Festival of Colors, is a Hindu celebration full of joy and one of India's most important holidays. During the day of the last full moon of the lunar month, usually late February or early March, the air is full of brightly colored powder (粉末). The festival is celebrated differently throughout the country, with bonfires and music, but the cheerful spirit is common among Hindu people around the world.

★ International Pillow Fight Day — Worldwide

    Tens of thousands of people took part in the 4th annual International Pillow Fight Day on April 2, 2013. From London to Vancouver to many other cities, the festival is held in more than 100 countries. So just bring a soft pillow in early April, and watch feathers fly.

    It is said that if you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise — and as a result, we are growing old unnecessarily soon.

    Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of aging could be slowed down. With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations. Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side parts of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual on economical faculties. Contraction of front and side parts — as cells die off — was observed in some subjects in their thirties, but it was still not evident in some sixty-and seventy-year-olds. Matsuzawa concluded from his tests that there is a simple way to the contraction normally connected with age — using the head.

    The findings show in general terms that contraction of the brain begins sooner in people in the country than in the town. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking (萎缩) brains as the farm worker, bus driver and shop assistant.

    Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain, good blood circulation is through using the brain.” he says. “Think hard and engage in conversation. Don't rely on pocket calculators.”

    When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it.

    Cigarettes? Cup of coffee? No, it's the third most addictive（使人上瘾的） thing in modern life, the cell phone. And experts say it is becoming more difficult for many people to curb their wishes to hug it more tightly than most of their personal relationships.

    With its shiny surface, its smooth and satisfying touch, the cell phone connects us to the world even as it disconnects us from people three feet away. It affects us in ways its inventors in the late 1940s never imagined.

    Dr. Chris Knippers, an expert at the Betty Ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on-one personal contact, and an escape from reality.

    Sounds extreme, but we've all witnessed the evidence: the person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Is it just rude, or is it a kind of unhealthiness? And pardon me, but how is this improving the quality of life?

    Jim Williams, an industrial sociologist based in Massachusetts, he points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e-mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances(熟人) through the Internet and cell phones have produced fewer friends,” he says.

    If the cell phone has truly had these effects, it's because it has become very widespread. In 1987, there were only 1 million cell phones in use. Today, almost 300 million Americans carry them. The number of cell phones is far more than that of wired phones in the United States.

    Your next car could have two seats, three wheels—two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car named the Elio. Its two seats sit front and back instead of side by side. The driver is positioned in the center with the passenger directly behind.

    The starting price for the car is just $6,800. It has only one door, on the left side, which cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it cheaper. It has air conditioning, power windows and door locks and an AM/FM radio. More features can be ordered through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

    Paul Elio dreamed as a kid that he would one day own a car company called Elio Motors. In 2008, tired of high gas prices, he started working on a car that burns gas in a more effective way. Equally important to him was creating US manufacturing jobs and making the car inexpensive enough to attract buyers who might otherwise be stuck in their old, unreliable cars. "Whatever matters to you, this can move the needle on it, he said.

    Already, more than 27,000 people have reserved one. Paul hopes to make 250,000 cars a year by 2020. So far, reservation holders are those who will use the Elio as a second or third car for work. Paul Elio believes the car will interest college students as well as used-car drivers who want something newer and more reliable, though.

    After some blood tests, Dr Stubs stood before me, a tall man, but short on personality and sporting a cold expression. You have systemic lupus, he said matter-of-factly. "Lupus," he continued, "is an auto-immune disease and …." I remember certain details but mostly I remember him talking about children. "Children are no harm. But childbirth would jumpstart additional symptoms that could be life threatening. You already have two kids anyway."

    As I got up to leave, shaken and drained, he said his parting words, "I would discourage any further research. There is no cure and nothing can prevent its progression."

    Still, I did research lupus and its symptoms tiredness and joint pain-were both consistent with what I was experiencing. And eventually some major organs could be affected, causing shutdown and possibly death.

    I studied and found out that echinacea had a record in making immune system stronger. I decided that along with the plant I would strengthen my mindset by immersing myself in my family with my one-year-old son and three-year-old daughter.

    After another visit, I decided never to go back to Dr. Stubs. How could one endure repeatedly hear desperately words coming from an emotionless mouth even though they were truth? The years passed. When I would feel tired and achy I pulled support from my children and their laughter.

    Finally, after eight years, I went to Dr. Kirstein who was recommended by a friend. She stood there holding my hand and looking into my eyes warmly.

    "So let's talk a little

    Instantly my defenses were down. Before I knew it, she had me running on and on about my children, my husband, my life and dreams. I told her about all the meaningful activities I was involved in, those things I might have never done without the disease.

    After several follow-up tests, and greater research into my family history, Dr. Kirsteincame to conclusive answer. I did not have systemic lupus. There must be something wrong with the initial tests 8 years before.

    I didn't know whether I should jump for joy or scream because I had been living the last eight years in fear of a fatal disease. But then I realized that I had been living every day, not so much in fear, but happiness Even day was a gift and I knew it.
