I mean, c'mon, a freakin gall-bladder?

last night was my first experience with morphine. administered through iv at the provo hospital i was born in. all this because i ate some carrots and then felt i was dying and fought it for four hours and finally went to the hospital only to learn that my frikin gall bladder was on the fritz. a gall bladder, what the heck does a gall bladder do anyway? (believe me, i have since googled it)
