In her book "Stiff: The Curious Lives of Human Cadavers," author Mary Roach discusses various intriguing aspects of human anatomy and the curious destinies of cadavers. One notable point she makes is the comparison between the size and weight of the human head and that of a roaster chicken. This analogy highlights the surprising similarities in physical characteristics, prompting readers to consider the complexities of the human body in a more relatable manner.

This comparison serves to engage the audience in a thoughtful exploration of human anatomy while also adding a touch of humor to a typically somber subject. By drawing parallels with familiar objects, Roach invites readers to reflect on the biological and cultural significance of human remains, encouraging a deeper understanding of life and death.
