Why are we compelled to bite a blister, giving it just a little pinch with our canines, even though everything in our wiring tells us that it will hurt.  Why expose that delicate pink flesh, hidden underneath and not-quite-ready-for-prime-time, to the air and elements?  It should be kept under the tough, bubbled, blister skin, until it's ready to take over for the soon to dry-up-and-fall-off stuff.  But no, we poke a hole in the protective blister skin as soon as we get the chance.  Why? To relieve pressure?  Nah.  Doctor's orders?  Nah.  No, we chow down on the blister bubble because God put that really tasty juice under there, that's why.

Thank you, God, for making blister juice so darned salty delicious and irresistible.
