Your fingernails, it’s been said, may reveal a lot about your general health. Nails in good condition should be smooth and color-consistent, but as you age, you may notice that your nails acquire vertical ridges or become more fragile. This isn’t something to be concerned about. You should be able to grow out any areas on your nails caused by accident without any issues.
