How Your World Works

On today's show, we talk to our good friend Rachel Rothman, Chief Technologist at the Good Housekeeping Institute. Working on a specialized floor a few levels up from Popular Mechanics, she and a team of engineers test stoves, clothes, food, cars--pretty much everything you encounter in day-to-day life. She explains how she got into such an exacting line of work, how it's heightened her neuroses (and given her new ones), and why it's ultimately so rewarding.
