As soon as I saw this survey I said, "Yep, that's me."  I'm one of those people who has an incredibly difficult time convincing myself to take a key off my keychain. 

According to the survey, the average person carries around NINE keys . . . but can only say for sure what SIX of them actually unlock.

 On average, women carry slightly more keys than men . . . women carry 10, men carry eight.  Women also usually remember what their keys open a little better than men.

 Almost one out of 10 people say they carry around more than 21 keys.

 Only 10% of people say if they lose their house keys, they have the locks changed . . . most people figure whoever found their keys won't find their house.

20% of people say they have a key "hidden" within 10 feet of their house.  Rocks are the most popular hiding place . . . slipping it under the doormat is second . . . and putting it under a car tire in the driveway is third.
