My left rib is sticks out a bit & has for years but no, I wasn't born with it. Why?

Answer 1

It it is not painful, you are spending altogether too much time staring at your self in the mirror in a frenzy of self-absorption. Do something meaningful with your time, ie read something that will expand your mind or understanding of the world, do something for someone else, volunteer your time at a hospital or other worthy endeavor.

I suspect that you are very young, so this is a good time to set some life goals and priorities. If you are over 30, likely that you will never get over this obsession with the physical self.
