“I love to walk. Walking is a spiritual journey and a reflection of living. Each of us must determine which path to take and how far to walk; we must find our own way, what is right for one may not be for another. There is no single right way to deal with late stage cancer, to live life or approach death, or to walk an old mission trail.”
― Edie Littlefield Sundby, The Mission Walker: I was given three months to live...

“Actually, the entire ascent of life can be presented as an adaptive radiation in the time dimension. From the beginning of replicating molecules to the formation of membrane-bounded cells, the formation of chromosomes, the origin of nucleated eukaryotes, the formation of multicellular organisms, the rise of endothermy, and the evolution of a large and highly complex central nervous system, each of these steps permitted the utilization of a different set of environmental resources, that is, the occupation of a different adaptive zone.”

“Come back. Even as a shadow, even as a dream.”
