A conversation with my bank illustrates how much detailed info they gather.

I wanted to do business but somehow had triggered one of their fraud alerts. So they asked me questions about where I lived 30 years ago, the color of a vehicle I owned 20 years ago, where I shopped, and so on. It was done in multiple choice format, and, yes I called them and verified the number.

No one's life is beyond notice for profit and power.
