because I have the same thing. My left rib cage sticks out a lot more than on the right. I also remember reading somewhere that this is somehow linked to liver and gallbladder problems. I can't remember how it was explained, but it had something to do with compensating for the weakness and it affects the posture and causes the left rib cage to protrude. I have a ton of congested liver and gallbladder symptoms and am planning on doing my first Liver Flush on Friday.
