Yeah I constantly have to go around making a funny face nowadays. The trick to a safe new face is to take 4 random words (for example: horse, clown, sad, elf-ears) and create your new face by imitatating that 24/7. Or you use a face manager (or make-up artist as it is called in non sec circles) so you just have to remember one face.

This is why I love the expression; (first heard, either here or on Slashdot)

Fingerprints are your login, not your password.

One thing I worry about is if/when the government(s) start using the same algorithms that industry is using to generate $HASH in all these biometric scanners. Some ugly version of the world where the local police department can search FBI+Apple+Google Fingerprint DB.
