Someday a stranger will read your email without your permission or scan the websites you've visited.
Or perhaps someone will casually glance through your credit card purchases or cell phone bills to find out
your shopping preferences or calling habits.
In fact,it's likely that some of these things have already happened to you.Who would watch you without
your permission ? It might be a spouse, a girlfriend, a marketing company, a boss, a cop or a criminal.
Whoever it is,they will see you in a way you never intended to be seen-21st century is the equal of being
caught naked.
Psychologists tell us boundaries (dividing line) are healthy,and that it's important to reveal yourself to
friends,family and lovers in stages,at appropriate times.But few boundaries remain.The digital bread pieces
you leave everywhere make it easy for strangers to reconstruct who you are,where you are and what you
like.In some cases,a simple Google search can reveal what you think.Like it or not,increasinglywe live in
a world where you simply cannot keep a secret.The key question is:Does that matter?
When opinion polls  (民意测验) ask Americans about privacy, most say they are concerned about
losing it. A survey found an overwhelming  (very large)  pessimism about privacy , with 60 percent of
respondents saying they feel their privacy is "slipping away,and that bothers me."
But people say one thing and do another.Only a  tiny part of  Americans change any behaviors  in an
effort to protect their privacy.Few people turn down a tollbooth  (收费站)  to avoid using the  EZPass
system that can track automobile movements. And few turn down supermarket loyalty cards. Privacy
economist Alissanfro Acquisti has a series of tests that reveal that people will give personal information
like Social Security numbers just to get their hands on a pitiful 50centoff coupon (优惠券)．
But privacy does matter-at least sometimes.It's like health；when you have it,you don't notice it.Only
when it's gone do you wish you'd done more to protect it.
