We doubt its useful, as no-one ever listens, but when you get dementia. a "Remember I said that" stick it to them, could be powerful about then? When you're dead too, if they think you had money, all the ears prick up. For such avaricious attentiveness, to help resolve wild goose chases from the grave, a "Remember I said that I always loved cats homes". could be useful.
Have a go at recording your own "Remember I said that" It does ask for a email address to send a copy of your responses. If you are worried about us spamming you. just use fake one It still works so you can get to spy on what others say.
It is for everyone so please share this on HFAO.blogspot.com "Humour for All Occasions". and keep your responses light so others can enjoy it too.
