I am an evolutionary throwback [occurring in less than 1% of the population] as I have a pair of extra ribs in my cervical spine.

I've got an extra nipple, which I used to think was a tiny mole, but now that I know what it is, it's really obvious. I also have some extra breast tissue, which I can feel on my ribs (but it isn't obvious to look at). I was also born with a hole in the skin at the bottom of my spine, which is residual from when our ancestors had tails. BTW The hole in my skin is the only one I would call an ailment, because I had to have an operation to correct it.
