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 121 st birthday．

　　When 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（寿命）?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（有弹性的）,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（物种）,one that ages at a slower speed,that would be a different story,he adds．

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

　　When Mary Moore began her high school in 1951, her mother told her, “Be sure and take a typing course so when this show business thing doesn't work out, you will have something to rely on．” Mary responded in typical teenage fashion．From that moment on, “the very last thing I ever thought about doing was taking a typing course, ” she recalls．

　　The show business thing worked out, of course．In her career, Mary won many awards．Only recently, when she began to write Growing Up Again, did she regret ignoring her mom, “I don't know how to use a computer, ” she admits．

　　Unlike her 1995 autobiography, After All, her second book is less about life as an award－winning actress and more about living with diabetes(糖尿病)。All the money from the book is intended for the Juvenile Diabetes Research Foundation(JDRF), an organization she serves as international chairman．“I feel there was a need for a book like this, ” she says．“I didn't want to lecture, but I wanted other diabetes to know that things get better when we are self－controlled and do our part in managing the disease．”

　　But she hasn't always practiced what she teaches．In her book, she describes that awful day, almost 40 years ago, when she received two pieces of life－changing news．First, she had lost the baby she was carrying and second, tests showed that she had diabetes．In a childlike act, she left the hospital and treated herself to a box of doughnuts(甜甜圈)．Years would pass before she realized she had to grow up－again－and take control of her diabetes, not let it control her．Only then did she kick her three－pack－a－day cigarette habit, overcome her addiction to alcohol, and begin to follow a balanced diet．

　　Although her disease has affected her eyesight and forced her to the sidelines of the dance floor, she refuses to fall into self－pity．“Everybody on earth asks, ‘why me? ’ about something or other,” she insists．“It doesn't do any good．No one is immune to heart pain, and disappointments．Sometimes we can make things better by helping others．I’ve come to realize the importance of that as I’ve grown up this second time．I want to speak out and be as helpful as I can be．”

　　Kelly Reeves was getting ready for a trip when her phone slipped into a sink full of water．Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked．Her first reaction? She got dressed, drove to the nearest store, and bought a new model at full price．

　　A new study finds that fear of losing your phone is a common illness．About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”．Interestingly, more women worry about losing their phone than men．

　　Fortunately, there's a solution．

　　The first step is to figure out if you have nomophobia．Checking your phone too often is one thing, but the true sign of a problem is that you can't conduct business or go about your routine when the fear becomes so severe．

　　Do you go to unusual lengths to make sure you have your phone? That's another sign of a problem．If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem．

　　Some of the treatments are similar to those for treating anxiety attacks： Leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety．Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone．

　　Of course, there are also technological alternatives．Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone．To find it, he can just go to a Web site and see the phone's location．

　　He also insures his phone through a service called Asurion．The company's description of its product reads like a prescription for anxiety： “60 million phones are lost, stolen or damaged each year．You'll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day! ”
