My fingernails have ridges. I've tried getting rid of them with buffers, but if I file the ridges down until they are even with the lowest part, they are thin and tear. They are corrugated. So I looked at the Mayo Clinic site. Evidently ridges are one of the aspects of aging. Well, there are worse, I assure you.
I had thought maybe taking some vitamin would help, or eating jello or something. Not.
So now I decided to do what Aunt Jenny did. She decided she liked them:)
