As we age, our bodies send subtle signals that something may be off internally. One of the lesser-known indicators comes from your fingernails and toenails. Changes in their appearance, particularly the presence of lines, ridges, or discoloration, can provide clues about your overall health.

-
Horizontal lines (Beau’s lines): Run across the width of the nail.
