How dangerous is it to give away personal info?

[lucee]

How bad does it have to get before you figure out that giving strangers personal information allows them to:
A. know where you bank, your account number and how to get into it
B. Know your credit card numbers and expiration dates
C. Know your mother's maiden name, an important piece of identity theft
D. know where you live, your marital status etc.
E. know your social security number and often your driver's license number, the two most important pieces of information necessary for identity theft.
F. What else do you need to know?
