its probobly like acid even if you leave it in a freezer for a year it still burns when you touch it so you will never know but in the bile's case zombies eat you
If you actually look at the bone structure of the hand, there is a "joined joint" below each of the phalanges(Fingers) called the metacarpals. They are stuck together with ligaments so the can't move independently of each other. What you see as the knuckles when you make a fist is actually the lateral edge of the metacarpals. /Anatomy lesson.

The bile that DOES hurt you in L4D2 is spitter goo, not boomer bile.
