" " Your office is the last place you want the sounds of your bathroom business to reverberate so everyone can hear them. Peter Cade/Getty Images There is no end to human ingenuity. Our brains instinctually find ways to solve problems. For example, during the Paleolithic period (roughly 2.5 million years ago to 10,000 B.C.E.), cavemen lived with painful blisters on their feet. Then one day, a regular Barney Rubble-type guy invented the shoe. Later, when the most stylish cave person couldn't stand to wear ugly shoes for another day, he designed the first loafer (not really). That ingenious problem-solving continues in the 21st century. Between social media, surveillance cameras, proctologists and naked yoga, privacy — like the remote — is hard to find. And don't bother looking for either in the bathroom. For this is the kingdom of bodily functions, where privacy, along with dignity, have no power.
