Expert Testimony || Blame it on Edison

"Why do roughly six billion humans sleep in a way that is contrary to what worked for millions of years? Because of a production that was once revolutionary and now costs less than two dollars: the lightbulb. The lamp next to your bed contains a device that has changed human sleep perhaps forever, and ushered in a new world of health problems that come from an overabundance of light."—Journalist and professor David K. Randall, author of Dreamland: Adventures in the Strange Science of Sleep
