I sewed through my finger on an industrial machine once (trust me, they really will sew through anything, gah!) and probably have no discernible fingerprints left after years of blade cuts, hot glue burns and unintentional chemical peels.
Also, I once had the needle shatter on a blind hemmer and a shard ricochet off my cornea. I left my glasses at home that day - what are the odds? The doctor thought that it went in (I kept hearing the phrase "inner-orbital foreign body" and got faint every time), but turned out to be a scratch on the cornea that was casting a shadow on my retina.
