We all come into existence as a single cell, smaller than a speck of dust

We all come into existence as a single cell, smaller than a speck of dust. Much smaller. Divide. Multiply. Add and subtract. Matter changes hands, atoms flow in and out, molecules pivot, proteins stitch together, mitochondria send out their oxidative dictates; we begin as a microscopic electrical storm. The lungs the brain the heart. Forty weeks later, six trillion cells get crushed in the vise of our mother’s birth canal and we howl. Then the world starts in on us. ~ Anthony Doerr, All The Light We Cannot See
