Pastimes, practices, and products that were once allowed—even encouraged—which you will never see again in modern America. There was a time, not long ago, when doctors would actually recommend smoking, and when we stored our food in toxic refrigerators, and unknowingly played with radioactive toys, flew down slides that ripped our skin off, and decorated our Christmas tree with ornaments made from asbestos. Fast-paced, informative, and a little bit scary – from perilous playgrounds to precarious products, it’s a running cavalcade of the most exciting, reckless, unsupervised tales of Americana in our history.
