Chew, bite, nibble, scratch, itch, protect, play, pick, poke, flaunt …tiny they seem but serve much purpose. Inconspicuous otherwise but in absence, nails are nothing but human claws made up of protein called ‘Keratin’. Sure they don’t hurt even as you shape them or clip them but they definitely spell what hurts your insides. While toe nails grow at a slow pace and take about 12 to 18 months to regrow completely; fingernails grow faster such that each of your finger has a brand new nail every 3 to 6 months. Hence fingernails are powerful health indicators of an early onset of disease and ill health.
