Tattoos have an uncanny ability to allow us the power of visual storytelling on our bodies. Whatever you want to convey about your life or personality, and however you would like to convey it, someone on the earth can draw up a tattoo of it and give that vision permanence on your skin.
In a way, scars, and birthmarks are also permanent visual storytellers on our bodies, though not ones of our own choosing. While some seek to cover-up what they think are "imperfections," others choose to accentuate their unique features with clever tattoos that are nothing short of incredible.
