I assume you have a bank account, and you vote,Gummie You buy things - groceries from the supermarket, clothes from various places, furniture from time to time, and you have grandchildren. Nothing exciting, just the usual boring life.
Your uneventful life is interesting to someone. The boring details can be sold to someone who makes a good living by knowing unexciting details about someone, and using them to their advantage.
Scammers and advertising/marketing people would be very interested to hear anything that would give them a clue to which bank you use, how you vote, which online clothes seller you use, whether you have grandchildren, what their names and ages are, and how much you spend on them.
The marketers would like to send you endless emails or texts with special discounts "just for you" with details of "sales" of stuff chosen to suit your taste and colour peferences, or your favourite meals, or children's items for exactly the same age and sex as your beloved grandchildren, or charming clothes that would look so great on them. If party politics in your area are aggressively conducted, you could find yourself harassed or threatened by someone who votes for the other lot.
The scammers could have a field day sending messages "from your bank" warning you of a dodgy transaction and giving you a number to ring to find out how to block it, which involves doing something which gives them the chance to access your account and do some dodgy stuff themselves. If your grandchildren are of age to be out and about after dark, you might receive a message from a (named) grandchild to say they have lost their phone and their wallet, so could you message them at their friends place (email address given) and send them money for a taxi home plus extra as friend has had to lend them money to buy a few drinks and a curry. Needless to say, while you worry, the grandchild will return safely with phone and wallet intact and know nothing of this.
