Skin. At roughly 20 pounds and 16% of your body weight it is the largest organ in the human body. It grows with us, stretching and expanding to cover the vast crevices and sinews within. It clings to our mass and stays with us, it adapts with our losses, our extensions, our embellishments. It is our ‘forever piece’, like that trusty pair of leather boots or favourite pair of jeans. It rarely gives way and it remains, embracing our bodies until the very end. The skin is a moving instrument, vital to everyday life and vitality. It is fragile – the cracks in the parched, overworked hands, the flush from the heat, the pallor of an ailment, all visible on the skin.
