     Whether you're headed to another country for business or pleasure, it is likely that you need to keep
in touch with family or business partners in the United States. But if you plan to do that using your cell
phone, you could have an unwelcome surprise-U.S. cell phones don't work abroad. U.S. companies use
different forms of technology, not like most of the international community, including Europe.
     However, there is an easy, cost-effective solution(方法) to staying in touch while you're traveling.
You Can rent a phone that is guaranteed to work in the countries you're visiting. Roadpost offers a 30-day cell phone rental plan that includes free incoming calls, free voicemail and call waiting services.
     The service is convenient and simple. You can place your order online and your phone will be shipped
to arrive on the date you want. If an unexpected business trip comes up, Roadpost can provide next-day
delivery for most cities. In addition to the phone, Roadpost provides a spare battery, travel charger and
a leather carrying case.
     When your phone is shipped from Roadpost, you receive an e-mail confirmation that contains your
international cell phone number so you can leave it with family members and business partners; Roadpost
even provides business cards preprinted with your international phone number.
     Those who don't want to be without e-mail while traveling can rent an international BlackBerry. It can
be hard to stay in touch by e-mail when traveling. With an international BlackBerry, you can email as
much as you like, without worrying about an expensive bill. If you're traveling to very remote areas, you
may want to consider renting a satellite phone: Because they receive their signals from satellites, these
phones work anywhere on the planet, including oceans and mountains. When you return, simply ship the
phone or BlackBerry back to Roadpost using the return kit the company provides.

How Long Can People Live?

  She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday.

  Whe n it comes to long life, Jeanne Calment is the world’s recordholder.She lived to the ripe old age of 122.So is 122 the upper limit to the human life span(壽命)?If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150-or beyond?

  Researchers don’t entirely agree on the answers.“Calment lived to 122, so it wouldn’t surprise me if someone alive today reaches 130 or 135,”says Jerry Shay at the University of Texas.

  Steve Austad at the University of Texas agrees.“People can live much longer than we think,”he says.“Experts used to say that humans couldn’t live past 110.When Calment blew past that age, they raised the number to 120.So why can’t we go higher?”

  The trouble with guessing how old people can live to be is that it’s all just guessing.“Anyone can make up a number,”says Rich Miller at the University of Michigan.“Usually the scientist who picks the highest number gets his name in Time magazine.”

  Won’t new anti-aging techniques keep us alive for centuries?Any cure, says Miller, for aging would probably keep most of us kicking until about 120.Researchers are working on treatments that lengthen the life span of mice by 50 percent at most.So, if the average human life span is about 80 years, says Miller,“adding another 50 percent would get you to 120.”

  So what can we conclude from this little disagreement among the researchers?That life span is flexible(有彈性的),but there is a limit, says George Martin of the University of Washington.“We can get flies to live 50 percent longer,”he says.“But a fly’s never going to live 150 years.”

  “Of course, if you became a new species(物種),one that ages at a slower speed, that would be a different story,”he adds.

  Does Martin really believe that humans could evolve(進(jìn)化)their way to longer life?“It’s pretty cool to think about it,”he says with a smile.
