Including your PW manager, how many complex PW do you have memorized?

I'm curious of your experience.

For instance, right now I have two complex passwords memorized. One is my PW manager master password and the other is my computer login where I can't copy/paste from my PW manager.

How many complex passwords do you have to memorize for similar reasons? How complex are they?
