Someday a stranger will read your e-mail without your permission or scan the Website 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 some of these things have already happened to you. Who would watch you without your permission? It might be a girlfriend,a marketing company, a boss or a criminal. Whoever it is,they will see you in a way you never wanted to be seen―the 21st century equivalent of being caught naked.

Psychologists(心理学家)tell us boundaries are healthy,and it' s important to show yourself to friends, family and lovers in stages,at appropriate times. But few boundaries remain. The digital bread crumbs (碎屑)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,increasingly we live in a world where you simply cannot keep a secret.

The key question is:Does that matter? For many Americans,the answer apparently is "no". 

When opinion polls(民意测试)ask Americans about privacy,most say they are concerned ab?out losing it. A survey found 60 percent of respondents say they feel their privacy is "slipping away, and that bothers me".

But people say one thing and do another. Only a few Americans change any behaviors in an effort to protect their privacy. Few people turn down a discount at tollbooths(收费站)to avoid using the EZ-Pass system that can track automobile movements. And few turn down supermarket loyalty cards. Many people will give up personal information like Social Security numbers just to get their hands on a pitiful 50-cents-off 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.
