Hence "Strong passwords that need to be memorized" in OP's comment. Or else your memory is way better than mine (or I care way less, or probably both).
It is possible to memorize a 100 bit password. I once had a 1000 word poem memorized, and could write it down flawlessly from memory.
I agree that it's not worth memorizing, you should instead use a password database. But I still maintain my original point that there's no reason to assume that your password will be leaked eventually if you use a strong password.
