1. Why did pirates wear eye patches?
It was actually a trick to help them see better. The eye with the patch was used to see in the dark below deck, while the uncovered eye was used for bright light above deck.
2. Your fingerprint isn't the only unique thing about you.
Our irises have over 256 unique characteristics. Compare that to fingerprints, which only have about 40. This is why many new security measures have iris scans instead of fingerprint scans.
