7 Things our Hands say About Our Health

hey're one of the most important parts of our body when it comes to day-to-day activities; without them we couldn't cut vegetables, grip pliers, or text our friends. They're revealing, too: Not only do scars and age spots recount our personal history but mystics all the way back to prehistory have "read" our futures in their lines and whorls.
