We don't want to give away too many spoilers but who would have guessed that we all have hundreds of tiny critters living in our eyelashes. Yes, you read that right! Gross eh? And they don't even pay you rent.
In fact, we are all absolutely covered in micro-organisms. So next time you scold the dog for bringing fleas into the house just remember you've got several billion uninvited guests camped out on your body. We're basically just huge housing estates for bugs! Yuk.
Anyway, before you run off to take a shower check out some more of our (mostly unpleasant) facts about the wonder that is the human body.
