Cells in human bodies replace themselves so regularly that, after seven years, the body is composed of microorganisms totally foreign to those seven years past. A finger or toenail takes about 6 months to grow from base to tip. Skin is shed and regrown over a period of roughly 27 days – a dozen new skins a year, a thousand in a lifetime. Only half an hour of every human’s life is spent as a single cellular organism – the time in which the egg is fertilized. The rate of transformation around and inside me is unfathomable. In fact, stagnation is, intrinsically, alien. Transformation is the most natural state of my existence.
