Who hasn’t done some online window shopping and the next thing you know your popup ads and ads in your email are related to the exact items you were looking at?
Security cams aren’t the only time we are being watched.
A few years ago, my wife and I were driving somewhere. Her cell phone was on but not being used. We were talking about porch furniture, and I happened to remark that Adirondack chairs were more comfortable than they looked. I hadn’t mentioned, or even thought of, Adirondack chairs in years, and have never owned one. Starting within the hour, and for the next month or two, we were getting all sorts of ads via phone and email for, you guessed it, Adirondack chairs.
This is why my own cell phone stays turned off in a drawer unless I specifically need to use it to make or receive calls. Probably doesn’t help much, since my wife keeps hers on all the time.
