10 Scientists Who Were Their Own Guinea Pigs

The hosts dive into the fascinating and often dangerous world of scientists who experimented on themselves throughout history, from the 16th century all the way to modern times. You'll learn about researchers who deliberately overdosed on morphine, lived on giant scales for 30 years, wore vision-reversing goggles for over a week, and even gave themselves blood transfusions to test their theories. These brave (or possibly crazy) scientists made groundbreaking discoveries about human metabolism, pain response, memory, and blood types by putting their own bodies on the line for science.
