The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.

Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.

A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a hose(软管) and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.

When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜函病). The bends can cause a diver to double up in pain. They can even kill him.

Babies are born yogis. Once we were all able to pull our toes up by our ears and laugh about it. Then we aged, got injured, and began carrying stress in our shoulders and back. In short, we lost our balance.

Yoga（瑜伽） is an ancient practice that helps create a sense of union in body, mind, and spirit. It brings us balance. I was seriously out of balance when I started practicing yoga in 1999. I had plantar fascitis in both feet, and my doctor had warned me against all the things I loved to do: walking, hiking, and playing tennis. I was desperate for exercise. Yoga became my salvation and even enhanced my other fitness activities. I practice yoga at least twice a week, but I consider yoga to be part of my daily life because after a while you no longer just practice yoga—you love it.

Yoga becomes part of your physical life. Your body grows stronger, more toned, and more flexible as you move from one pose to the other. I spent a week in Mexico at a yoga retreat, and it was the first vacation on which I lost weight. “Rather than building muscle, yoga builds muscle tone,” says Shakta Kaur Khalsa, author of the K.I.S.S. Guide to Yoga. “Because yoga helps maintain a balanced metabolism (新陈代谢), it also helps to regulate weight. Additionally, yoga stretches muscles lengthwise, causing fat to be removed around the cells.” I do yoga poses throughout the day. After hours at my computer, I stretch my stiff shoulders and arms. When I need a boost of energy, I do energizing poses. When I am feeling exhausted at the end of the day, I do restorative poses.

Yoga becomes part of your mental life. Yoga teaches you to focus on breathing while you hold the poses. This attention to breath is calming; it dissolves stress and anxiety. I use yogic breathing on the tennis courts, in the dentist’s chair, and in traffic jams. You should always leave a yoga practice feeling energized, not tired. If you feel tired after yoga, it means you spent the time “fighting” yourself, trying to force yourself into poses. In yoga, you “surrender” to the pose by letting go of the tension.

Yoga becomes part of your spiritual life. Yoga is practiced by people from all religions; it is not restricted to any religious group. Yoga teaches “right” living in how we deal with ourselves and others. As I work on a difficult pose, I learn patience, forgiveness, and the value of gentleness. Yoga advocates proper eating, but you don’t have to be a vegetarian to practice yoga.

People tend to think of computers as isolated machines, working away all by themselves. Some personal computers do without an outside link, like someone's secret cabin in the woods. But just as most of homes are tied to a community by streets, bus routes and electric lines, computers that exchange intelligence are part of a community local, national and even global network joined by telephone connections.

　　The computer network is a creation of the electric age, but it is based on old-fashioned trust. It cannot work without trust. A rogue (流氓) loose in a computer system called hacker is worse than a thief entering your house. He could go through anyone's electronic mail or add to, change or delete anything in the information stored in the computer's memory. He could even take control of the entire system by inserting his own instructions in the software that runs it. He could shut the computer down whenever he wished, and no one could stop him. Then he could program the computer to erase any sign of his ever having been there.

Hacking, our electronic-age term for computer break-in is more and more in the news, intelligent kids vandalizing（破坏）university records, even pranking (恶作剧) about in supposedly safeguarded systems. To those who understand how computer networks are increasingly regulating life in the late 20th century, these are not laughing matters. A potential for disaster is building: A dissatisfied former insurance-company employee wipes out information from some files; A student sends out a "virus", a secret and destructive command, over a national network. The virus copies itself at lightning speed, jamming the entire network thousands of academic, commercial and government computer systems. Such disastrous cases have already occurred. Now exists the possibility of terrorism by computer. Destroging a system responsible for air-traffic control at a busy airport, or knocking out the telephones of a major city, is a relatively easy way to spread panic. Yet neither business nor government has done enough to strengthen its defenses against attack. For one thing, such defenses are expensive; for another, they may interrupt communication, the main reason for using computers in the first place.
