This quote emanates from Mary Roach's exploration of the human body and its myriad peculiarities. The phrase highlights the humor and curiosity that Roach infuses into her scientific writing. The lacrimal glands, responsible for producing tears, are typically associated with the emotional and physiological responses we have to empathy, sadness, or even joy. By stating there wasn't an 'anhydrous' (meaning 'without water') lacrimal gland, Roach may be suggesting a humorous exaggeration that the body was devoid of certain features or functions necessary for tear production. This not only emphasizes the complexity and sometimes bizarre nature of human anatomy but also reflects Roach's style of making science accessible and engaging. As a reader, you are invited to reconsider the ordinary processes we take for granted, appreciating the intricate balancing act of physiologic mechanisms. Roach's wit serves to demystify the often intimidating world of anatomy, revealing that even seemingly straightforward features like tear glands have their own mysteries and quirks. Furthermore, this phrase underscores the theme that the human body, in all its complexity, can be viewed as both a marvel and a source of constant curiosity. Her focus on such diminutive yet significant structures champions the idea that every small detail in our anatomy matters, often holding surprising significance when examined closely. This quote exemplifies her broader mission to celebrate the curious, sometimes comical, intricacies of life and death, encouraging readers to approach the science of the body with both humor and respect.
