The Future of Technology

    William, a businessman, arrives in a foreign airport. He doesn't show his passport. Instead, a machine in the wall reads the computer chip（芯片）in his arm. This contains information about him: his name, age, and I.D number. He exits the airport, and a car door opens when it “sees” him. The car takes him to his hotel. His room “knows” he has entered the building and it “reads” his body. He is cold, so the room becomes warmer. William then watches a business presentation on a video wall. When he takes a bath, the presentation “follows him and continues ”on the bathroom wall. Finally, the room plays music to help him sleep. It turns off the music when it “sees” him sleeping.

    William doesn't exist, and none of this is real. But it might be soon. “In five to ten years, computing and communications are going to be free and everywhere, in your walls, in your car, on your body,” says Victor Zue, leader of Project Oxygen.

    Project Oxygen has one big idea: to create better relationships between machines and people. The dream is that computer will learn to understand what people want.

    So, what changes will there be at work? Firstly, the building will know where everyone is, all the time. You want to talk to someone? Type the person's name on the nearest computer. It will show you a map of the building and exactly where this person is. You then call this person, who picks up the nearest telephone, also shown on the computer. If he or she is busy with a client（客户）or in a meeting, the computer will tell you.

    Is all this really possible? Visit the Siebel Center, Illinois and see for yourself: computers in the doors and walls, cameras everywhere, the technology of the future, but here today.

    Aging brings wrinkles, sagging bodies and frustrating forgetfulness. But getting older is not all bad for many people. Mounting evidence suggests aging may be a key to happiness. There is conflicting research on the subject, however, and experts say it may all boil down to this: Attitude is everything.

    Older adults tend to be more optimistic and have a more positive outlook on life than their younger and stressed opposites. The big question is why seniors are happier. A recent study suggests one reason: Older adults remember the past through happy memories. Aging can bring more cheer as people become more comfortable with themselves and their roles in society. The older adults said they were enjoying more time with their family, spending more time on hobbies and having greater financial security and did not have to work.

    But others are doubtful about the link between happiness and growing older.

    "The notion that those in old age are happiest is misleading," said Richard Easterlin, a professor of economics at the University of Southern California. "It is based on comparing people of different ages who are the same in terms of income, health, family life." Easterlin added, "When you take account of the fact that older people have lower income than younger, are less healthy, and more likely to be living alone, then you will find it hard to accept that they are happier.

    In fact, scientists have found that as people age, their health declines and social networks disappear as their friends die, which can make the elderly less happy.

    Even if one does give in to age's dark side, health and happiness don't always go hand-in-hand. It's all about attitude. Research by the University of Chicago's Yang suggests that attitude about life and happiness, is partly shaped by the era in which a person was born. It turns out that individuals who adapt the best to changes also have the highest expected levels of happiness.

 Despite the conflicting findings about aging and happiness, the good news is that there doesn't appear to be a limit to how much happiness one can achieve in one's life. “Most people desire happiness,” Easterlin said. “To my knowledge, no one has identified a limit to attainable happiness.”

    I went online to check if my pay was in my bank account. To my amazement, I discovered that not only had I been paid, a company I'd never worked for had also paid me! I knew I'd have been beside myself if my own salary was not in my account, so I tried to get the money back to the right person. It is easier said than done.

    The bank couldn't help as it wasn't a bank problem. The human-resource department as the company that paid me was unable to help as I didn't have enough details. I rang the bank again. Thankfully I had sympathetic call operator who gave me a name, so I again rang the company “Daniel” worked for.

    I expected the bank would contact me to arrange to take the money from my account and repay Daniel. I heard nothing for a month and the money remained in my account when Daniel called, explaining he'd tried to get back his money but had been unsuccessful as neither the bank nor his company felt it was their error. He had rung to ask if I could speak to the bank, but after chatting for a few minutes we realized we could probably fix this problem ourselves.

    We decided I would take the money from my account and he would pick it up from me. Due to my busy job I was unable to meet Daniel personally but he left me a lovely bottle of wine in exchange for what was rightfully his. I never had any intention of keeping Daniel's pay, but red tape（繁琐手续）made it difficult to do the right thing. It all came down to two people being able to do what a huge bank and a large company couldn't do — admit a mistake has occurred and fix it.

    This is my son Matthew's last night at home before college. I know that this is good news. I feel proud that Matthew will go to a great school. I know that this is finest hour. But looking at the suitcases on his bed sends me out of the room to a hidden corner where I can't stop crying.

    Through the sorrow, I feel a rising embarrassment. "Pull yourself together!" I tell myself. There are parents sending their kids off to battle zones. How dare I feel so shocked and upset?

    One of the great gifts of my life has been having my boys, Matthew and Johnowen. Through them, I have explored the mysterious, complicated bond between fathers and sons. As my wife and I raised them, I have discovered the love and loss between my father and me. After my parents' divorce，I spent weekends with my dad in Ohio. By the time Sunday came around, I was unable to enjoy the day's activities because I was already afraid of the goodbye of the evening.

    Now，standing among Matthew's accumulation of possessions, I realize it's me who has become a boy again. All my sadness and longing to hold on to things are back, sweeping over me as they did when I was a child.

    His bed is tidy and spare. It already has the feel of a guest bed. In my mind I replay wrapping him in his favorite blanket. That was our nightly routine until one evening he said," Daddy, I don't think I need a blanket tonight." I think of all the times we lay among the covers reading. I look at the bed and think of all the recent times I was annoyed at how late he was sleeping. I'll never have to worry about that again, I realize.

    For his part, Matthew has been a rock. He is treating his leaving as just another day at the office. And I'm glad. After all, someone's got to be strong. I'm proud that he is charging into the first chapter of his adult life with such confidence.

    The bus screamed to a stop in Nazareth, Israel. Five Australian backpackers boarded and struck up a conversation with me. They asked typical travelers' questions—where was I going and why was I traveling alone? My plan was to travel with a friend of a friend, I explained, but when I called her that morning, she didn't pick up and I had no other way to reach her. My stomach was in knots, but I decided to head out anyway, thinking I might run into her if I traveled to Tiberius, where we had planned to go together.

    "Why don't you travel with us?" one of the backpackers offered. They were experienced adventurers who would work for a few months, save, then travel for as long as they could. Their current plan was to explore the Middle East and Europe in three months while working in London.

    It seemed risky to travel with strangers, but my instinct said yes. For the next two weeks, I explored Israel with the backpackers and learned to trust my instincts in all types of new and interesting situations. When they hook a ride, I took the bus, but when they wanted to steal into the King David Hotel's swimming pool, I led the way. The world opened up to me because I chose to travel alone. I joined complete strangers, who become close friends. Years later, one couple from the backpacking group even flew from Sydney to Phoenix to be in my wedding. The trip was such a special experience that it gave me confidence in all areas of my life. Since then, I've backpacked alone across South Africa, sky-dived from 12,000 feet in New Zealand and even moved across the U.S. with no job lined up.

    On my third day wandering in Israel with my new friends, I bumped into the woman I was supposed to meet. Though I was happy she was all right, I was grateful she hadn't picked up the phone.

    Many of us just laugh it away when they are told incredible (难以置信的) stories about other people, but I have a deep interest in these stories and I prefer to believe they are true. Here's one I collected from a total stranger.

    "Well, I was 11 when my family arrived at Fern Lake overlooking Trail Ridge Road in Rocky Mountain National Park. It was so beautiful to look miles across the Rockies and thousands of feet below into the valley. My parents were busy getting lunch out of the trunk so I climbed over the wooden fence to get closer to the cliff edge in the hope that I wouldn't miss any beautiful sight down there.

    I started down a little hill but soon started sliding on loose pebble rocks(鹅卵石). I fell on my back, but kept going faster and faster to what seemed the edge of the world (a 2,000 foot drop). In seconds I knew I was going to die. My feet and legs went first over the edge at a high speed. Then suddenly I felt two hands push hard on my chest and stopped me dead. My heart was racing and I slowly inched my body back to where I finally could make it back up the hill.

    My father was waiting there and screaming at me for doing such a dangerous stunt (特技). I tried to tell him and my mom about the hands that held me back, but to this day they don't believe me. They thought I was just trying to get out of trouble with a made-up story.”

    We parted ways, but I assured her that I believed every word of her story. I could see a little surprise and happiness on her face.

    That's why I always ask people to share their miracles (奇迹). Each real story makes my days full of hope and gratefulness.
