Motherhood is a career to respect
A WOMAN renewing her driver’s license at the CountyClerk’s office was asked to state her occupation. She hesitated, uncertain how to classify herself.
“What I mean is,” explained the recorder, “do you have a job, or are you just a...”
“Of course I have a job,” said Emily. “I’m a mother.”
“We don’t list ‘mother’ as an occupation... ‘housewife’ covers it,” said the recorder.
One day I found myself in the same situation. The Clerk was obviously a career woman, confident and possessed of a high sounding title. “What is your occupation?” she asked.
The words simply popped out. “I’m a Research Associate (研究员) in the field of Child Development and Human Relations.”
The clerk paused, ballpoint pen frozen in midair.
I repeated the title slowly, then I stared with wonder as my pronouncement (声明) was written in bold, black ink on the official questionnaire.
“Might I ask,” said the clerk with interest, “just what you do in your field?”
Coolly, without any trace of panic in my voice, I heard myself reply, “I have a continuing program of research (what mother doesn’t), in the laboratory and in the field (normally I would have said indoors and out). Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it). But the job is more challenging than most careers and the rewards are more of a satisfaction rather than just money.”
There was an increasing note of respect in the clerk’s voice as she completed the form, stood up, and showed me out.
As I drove into our driveway, buoyed up (激励) by my glamorous new career, I was greeted by my lab assistants – ages 13, 7, and 3.
Upstairs I could hear our new experimental model (a 6-month-old baby), in the child-development program, testing out a new vocal pattern.
I felt proud! I had gone on the official records as someone more distinguished and indispensable (不可缺少的) to mankind than “just another mother.”
Motherhood... What a glorious career! Especially when there’s a title on the door.

Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health．
This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased．Apple, for example, doesn’t want iP hones to come closer to you than 1．5 centimeters; Research In Motion, Blackberry’s manufacturer, recommends 2.5 centimeters．
If health issues arise from cell phone use, the implications are huge．Voice calls - Americans chat on cell phones 2．26 trillion minutes annually - generate $109 billion for the wireless carriers．
Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
"Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen.
