Leukonychia.

The other day after church I looked down at my fingernails and noticed something. They were clear. Every one of them. I usually have this sort of miniature white cloud in the middle of my nail. I never knew what it was until today.

Leukonychia (also known as "White nails") is a medical term for white discoloration appearing on nails. It is derived from the Greek words 'Leuko' which means 'white' and 'Onyx' which means 'nail'. The most common cause is injury to the base of the nail (the matrix) where the nail is formed. But I think there's something else -like another reason why the little white clouds appear. Lack of something or something. Oh, here's something: (I found it on beautytips.ygoy.com) Other probable causes for this discoloration are arsenic poisoning, heart disease, renal failure, pneumonia, ill health, vitamin deficiency or hypoalbuminemia.

So yeah. Now you know.
