Introduction

In this chapter, they discuss various topics including time travel, seahorse reproduction, and the effects of worms on the human body. They mention a strange hypothesis that having worms can improve certain aspects of health, although they caution against purposely infecting oneself with worms. They also talk about a case where a woman had a worm in her brain and how a drug called Ivermectin was not effective in treating it due to the blood-brain barrier.
