'Hazardous History With Henry Winkler' explores a time when safety regulations were lax, and consumer awareness was limited. The series covers a wide range of topics, from dangerous toys and foods to hazardous industrial practices.
One particularly interesting segment features pro wrestling bears. During the 1960s and 70s, it was not uncommon to see bears wrestling humans as a form of entertainment. Terrible Ted, one of the most famous wrestling bears, even lived with Stu Hart's family.
The show also examines the inclusion of mind-altering drugs in carbonated beverages, such as lithium in 7UP. These examples illustrate a lack of understanding regarding the long-term effects of these substances.
Another segment explores the dangers of early 20th-century roller coasters, which lacked safety belts and exposed riders to extreme G-forces. The show also touches on metal-spiked lawn darts and asbestos used as fake snow.
