Covers people who have eaten all manner of things, have poisoned themselves, have tried to tech chimp to become low IQ worker and pushed their own bodies to the limits of what they could do.
The chapter on electricity is fascinating, as this was an age of discovery. The psychology chapter has been covered in greater detail in other books, but fits well in here. Some of the things that scientists and the military industrial complex wanted to do with nuclear bombs is quiet scary. The final chapter is gross.
