I just activated my new VISA card, which means I had to dispose of my old one. I don't just dispose of old cards, I obliterate them. I always cut them up into tiny pieces before throwing them up. Then I throw out the pieces into separate garbage bags. Yes, I know this is way over-kill ... but somehow very satisfying
Also, I never throw away any piece of paper with our signatures, address, financial numbers, etc without shredding it first.
How about you guys? How freakish are you about protecting personal information?
