When Panu takes up residence in her tiny home, she will join a movement that traces its roots to Henry David Thoreau, who wrote in "Walden," published in 1854, of his desire "to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived." The writer and abolitionist built his own abode at Walden Pond, in Massachusetts.
