Who can't remember their insurer, for crying out loud?
Maybe you are young and have just one car. But in my dotage at 70 and with three cars and a bike, I havent got a clue who they are insured with. Whats more I cant remember any of their reg numbers. And no, I havent got dementia.
But I can remember all my bank account passwords. Some things are worth remembering, others arent.
