You want kind of deep? Given how we change psychology, and physically as we age, are you literally the same person today as you were a decade or two ago?

Or mundane: How much harder did our grandparents have it, (or mine anyway), living where winter means at least three months of extreme cold; and why didn't they move somewhere warmer?

Or weird: Why are morticians allowed to just pour all of that blood down any old drain? And why hasn't anyone made a horror movie about blood-drinking bacteria, that evolved to subsist on it, living under mortuaries, somehow infecting the rats and raccoons that live in the drainage tunnels, turning them into blood thirsty monsters?

Or super quotidian: What's the weather like where you are? It's 17 degrees fahrenheit here, as I type this.
