12．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 that some of these things have already happened to you．Who would watch you without your permission？It might be a wife，a girlfriend，a marketing company，a cop or a criminal．Whoever it is？They will see you in a way you never intended to be seen．
Experts say it's important to introduce yourself to friends，family and lovers in stages，at proper times．But when you surf the Internet，the digital tracks you leave 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 give away what you think．Like it or not，increasingly we live in a world where you simply cannot keep a secret．
When Americans are asked about privacy（隐私），most say they are concerned about losing it．A survey shows that 60percent of Americans 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 preserve 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．A privacy economist has run a series of tests that show people will surrender personal information like Social Security numbers just to get their hands on a pitiful 50-cent-off coupon（优惠卷）．
But privacy does matter-at least sometime．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．
