Clothes can make phone calls, play music, dial your pal's number, keep you warm during cold weather and operate your computer.

This is not a fantasy. A British company, called electrotexiles, has created a wide range of clothes—clothes tha have minds of their own ! Scientists, working for the company, have invented a kind of fabric that can be mixed with flexible electronic materials to create intelligent clothing. The results are electronic garments.

If you think the weather has to be wired to different devices, think again. These designer clothes are wirefree, soft to touch and washable! Like any electronic device, these hightech clothes have to be powered. Currently, a tiny ninevolt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. These clothes are 100% shockproof, they say.

The electrotexiles team has also created the world's first cloth keyboard. These keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These “laptap” devices are all set to take over laptop computers!

Another useful garment is the shirtcummobile phone. This handy invention enables drivers to chat comfortably with others at the wheel! Other popular electronic wears include the denim (牛仔布) jacket with flexible earphones sewn into the hoop and the electronic ski jacket with a builtin heater. The ski jacket is also programmed to send signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.

Having completed the cloth keyboard, scientists have already started to work on a new project—a necktie that can be used as a computer mouse. What is the next? Do you have any idea?

There is nothing else but economy that occupies the minds of Americans at present times of economic crisis（危机）. The statistics on unemployment，housing costs and consumer confidence keep coming and coming，leaving people not just scared to spend money but also very stressed and emotionally exhausted. This stress has an effect on everything，starting with our sleep，mood，physical health，relationships and eating habits.

“Time of economic stress leads to increase rates of depression(忧郁)，”says Dr. Christopher Palmer，director of continuing education at McLean Hospital in Belmont，Massachusetts. “It worsens illness in people who have been constantly depressed. But it also causes new cases of depression. Just the fear of losing one’s job can put people over the edge. ”

And，without any doubt，just depression alone can create a variety of bad health effects.

33 percent of Americans reported that they have lost sleep due to the economic crisis. 26 percent say they are sleeping less than 6 hours per night，which is considered to be at least one hour less than the most favorable 7 to 8 hours recommended by sleep experts.

●Mental health，stress and heart attack

80 percent of Americans reported that last year the economy is a huge source of stress; 49 percent said the situation makes them feel nervous or anxious; 48 percent reported that they feel very sad and have developed depression.

Nearly twice the risk of heart attack or death was found in patients with the highest levels of depression or anxiety. Among those individuals，a 10 percent higher rise of heart attack or death was found in those whose anxiety rose over time.

The bedroom door opened and a light went on, signaling an end to nap time．The toddle（初学走路的婴儿）, sleepy-eyed, clambered to a swinging stand in his crib．He smiled, reached out to his father, and uttered what is fast becoming the cry of his generation: "iPhone!"

Just as adults have a hard time putting down their iPhones, so the device is now the Toy of Choice for many 1-, 2- and 3-year-olds．The phenomenon is attracting the attention and concern of some childhood development specialists．

Natasha Sykes, a mother of two in Atlanta, remembers the first time her daughter, Kelsey, now 3 but then barely 2 years old, held her husband's iPhone．"She pressed the button and it lit up．I just remember her eyes．It was like 'Whoa!' "The parents were charmed by their daughter's fascination．But then, said Ms．Sykes （herself a Black Berry user）, "She got serious about the phone．" Kelsey would ask for it．Then she'd cry for it．"It was like she'd always want the phone," Ms．Sykes said．

Apple, the iPhone's designer and manufacturer, has built its success on machines so user-friendly that even technologically blinded adults can figure out how to work them, so it makes sense that sophisticated children would follow．Tap a picture on the screen and something happens．What could be more fun?

The sleepy-eyed toddler who called for the iPhone is one of hundreds of iPhone-loving toddlers whose parents are often proud of their offspring's ability to slide fat fingers across the gadget's screen and pull up photographs of their choice．

Many iPhone apps on the market are aimed directly at preschoolers, many of them labeled "educational," such as Toddler Teasers: Shapes, which asks the child to tap a circle or square or triangle; and Pocket Zoo, which streams live video of animals at zoos around the world．

Along with fears about dropping and damage, however, many parents sharing iPhones with their young ones feel guilty．They wonder whether it is indeed an educational tool, or a passive amusement like television．The American Academy of Pediatrics is continually reassessing its guidelines to address new forms of "screen time．" Dr．Gwenn Schurgin O'Keeffe, a member of the academy's council, said, "We always try to throw in the latest technology, but the cellphone industry is becoming so complex that we always come back to the table and wonder- Should we have a specific guideline for them?"

Tovah P. Klein, the director of a research center for Toddler Development worries that fixation on the iPhone screen every time a child is out with parents will limit the child's ability to experience the wider world.

As with TV in earlier generations, the world is increasingly divided into those parents who do allow iPhone use and those who don't. A recent post on UrbanBaby.com, asked if anyone had found that their child was more interested in playing with their iPhone than with real toys. The Don't mothers said on the Website: "We don't let our toddler touch our iPhones ... it takes away from creative play." "Please ... just say no. It is not too hard to distract a toddler with, say ... a book."

Kathy Hirsh-Pasek, a psychology professor who specializes in early language development, sides with the Don'ts. Research shows that children learn best through activities that help them adapt to the particular situation at hand and interacting with a screen doesn't qualify, she said.

Still, Dr. Hirsh-Pasek, struck on a recent visit to New York City by how many parents were handing over their iPhones to their little children in tha subway, said she understands the impulse (冲动). "This is a magical phone," she said. "I must admit I'm addicted to this phone."
