What Vertical Lines on Your Nails Can Reveal About Aging – story-veterans.com

Many people first see them after 40, and in most cases, they are completely normal. These lines are known as vertical or longitudinal nail ridges. They are usually a natural part of aging, similar to wrinkles in the skin or changes in hair texture. Nails evolve as the body matures, and these subtle changes are generally harmless.
