Passwords and PINs

I am a professional password forgetter. I also have tendency to blank out in front of cash machines. What was that damn PIN number anyway? It's technology's greatest revenge on man, the password and PIN curse. To be fair to people like me, how many of these damn things can a man or woman remember really. I once thought I would be really smart and had one common password to all ills but kind of ended up being locked out of life. Maybe, all computers, cash machines should have retina readers. Yeah, that would be nice. One eye opens all.
