sadly enough, my own mother is facebook addict, sharing everything personal on iCloud, gmail or Facebook. When I warn her about that she even gave the "got nothing to hide" argument, with the "if they got money/time to loose on me sharing pics of my cats, good for them!"...
whereas she fled away from the Romanian/soviet dictatorship of Ceaușescu, having the Securitate secret police torture and deport parents and friends.
And though not that far, she's under that "65 y/o". But I won't give up repeating that argument that all that is wrong!
