One day, not too long ago, I sneezed too hard and my body turned completely inside out. My organs, unprotected by skin and muscle, felt the cold outside air like thousands of icy needles. All was dark as I peered inward. Enough light entered through my throat and interstitial crevices that I could make out some details in my new interior. My skin was on the inside, all shriveled up. So was my hair. So, I thought, this had been the exterior that I had been showing to people. Nothing much to look at now, was it?
