this is some totally useless info but here is the deal with the nail indents
When a person suffers a serious injury or illness the nails get pits in them. And those are actually so accurate that when bodies from a long time ago, like the frozen ice man, thousands of years old, they can use the indents in his fingernails to see illness or injury in his life.
i know that was useless to know,lol.
But anyway, it has something to do with your body needing so much to sustain itself during a serious health time that it takes away from things like nails and hair (which is why so many lose hair after a serious flare) becaue those are not as necessary for survival as your liver or heart.
