Author's Note: Does your body really replace itself every 7 years?

Goodbye cerebral cortex, I'm pretty sure I've lost the capacity to think. Like Elvis, my brain cells appear to have left the building. I spent a solid half an hour scouring my apartment for my wallet this morning. I checked all the usual targets – various tables and night stands – until I recalled that the last time I remembered having it was at the grocery store. So I opened the fridge and there was my cash, right between the milk and the eggs.
