Oooh dear I shouldn't admit out in the open but I do exactly the same as you Richie in my address book.
However if anyone nicks my handbag I'll be up shit creek!
As for passwords I know you're supposed to have lots of different ones but I tend to have very few and anything that varies from my norm I forget!!!! Had to keep changing passwords on Facebook and Ravelry as I register on these sites which I don't then use much and forget.

As for all the questions for internet (phone) banking OH MY GOD - because I use my bank online these days on the very few occasions I have to phone them I need to remember all my memorable this that and the others which I made up over 20 years ago.... how REALLY old people cope I just don't know as I'm old enough (but not yet 50

) and my brain is already addled!
Oh and our French bank cards don't give you the option to change the number to one that you can remember easily - whether that's a good thing or not I don't know!
I don't even know my own phone number - I have to look that up in my address book too.
