Introduction
The Practice of Using Cellulose
My book is not a medical manual and not a diet program. It is a set of reflections, experiences, and observations gathered over time. The ideas come from personal experimentation, from reading, from watching the body carefully, and from thinking about the relationship between humans and the microscopic world that inhabits us.
The chapters draw from a series of small essays written over the years — on the body and mind, on fasting, on the brain, on yoga, on pets, on the nature of being human, and on the possibility that caring for the biome may be one of the central responsibilities of human life.
Taken together they form a simple memoir: the story of someone who decided to take cellulose seriously.
