I'm extraordinarily curious how, and within which areas,our FINGERNAILS can reveal info. around our broad form.Anyone?

I once read an article, stating that examining the condition of your nails, can hold out information and insight, into the state of our over-all health?
I enjoy vertical ridges on my finger-nails, that I can visibly see, and even slightly feel, and see brownish-black horizontal lines about 1cm long. Does anyone own information as to what these could possibly mean? Anything else relevant on the subject , would be of great interest to me also, and severely much appreciated. Below, is a brief outline of my current Physical and Emotional health. Is near a direct correlation between anything here, and nail condition?
PHYSICAL -
I try to allege a healthy diet, incorporating moderate exercise, a conceivably healthy diet (not impeccable) and lift supplements Iron, Vitamin B Complex, and Omega 3 Fish Oil Capsules on a daily spring.
EMOTIONAL-

I'd articulate the emotional problems are of more concern to both you and your children than your fingernails,but that's only me. Men who are emotionally abusive uncommonly change,so catch out,doesn't help your kids to see that,that's purely creating the next contemporaries of abusers. As for the fingernails,if you've ever worn acrylic nails,that could be factor of the ridge problem. Look up nail diseases online.
