Log ins and passwords

I have so many log in names and passwords for various accounts on line. It's a new identity I have to keep recreating every time I want to look at a site in depth or buy something on-line.
I try to keep my passwords in a theme. (I'm not going to tell you what that theme is.)
But as the hackers get more advanced, the passwords and log ins you create need to be more advanced as well. Where as a five letter passwords used to work, now you have to come up with a nine digit password complete with letters, numbers and at least one of these: ##%%&*(()%$!
How am I ever going to remember something like: smlt#ts40 ? I ask you!

I have a file in my office of what my passwords are at various sites. This is supposed to help.
Without it, I'm lost.

What am I going to do if Alzheimer's ever sets in and I can't access my email anymore ? We're all screwed.

I predict that there is going to be some kind of fall out from all these passwords and log ins. Just you wait. I can feel it. It's nine digit now - but what about in 10 years? Will we be asked for a 25 digit password? I don't know.
Oh, and I also predict that Madonna and her daughter Lourdes are going to sing a duet together in the future. Lourdes is just going to sing on the chorus of one of Madonna's songs. (I dreamt this the other night. Yes, I dream about Madonna).
