Just be aware of how you use your debit/credit cards. Everything you buy is recorded somewhere, sold to marketers etc. Let an insurance company know how much you spend on cigarettes, booze, fast food... I'm guessing your rates could vary accordingly..
Now I'm not a big conspiracy theorist or anything like that, I'd just prefer to use cash most of the time and remain anonymous. And if you ask nicely, you can almost always get 5% off by paying cash..
carry on.
