It seems harmless, and you might even learn something you didn't know about your friends.

However, this fun game can also help identity thieves steal from you. Many banks, credit cards and other businesses ask for your place of birth as a way to reset your password.

The Texas Department of Public Safety says the personal information you should never give out includes: your social security number, driver license number or account number(s), date of birth, place of birth, home address, mother’s maiden name or passwords.

Knowing your date of birth and your place of birth can help lead identity thieves to the first three digits of your Social Security number.

Last year, the Federal Trade Commission received more than 680,000 complaints of identity theft. On its Web site, the city of Fort Collins warns that despite your best efforts to manage your personal information, skilled identity thieves may still gain access to your personal data. That's another reason to keep as much of your personal information private as possible.

If you use Facebook, now is a good time to look at your profile page. If you list your birth date, make sure you remove the year. If you list your children, consider removing them, especially if you use one of child's names or a combination of your children's names as a password.
