Vesta J. Farnsworth, The House We Live In; or, The Making of the Body
“ Every time we think, move, play, or work, some part becomes worn, and must be mended. Blood, the care-taker, passes swiftly around every part, first up, then down; and every trip she makes, the bones take something to mend them; the flesh takes its part; the skin must have a share; the hair and finger-nails take something to make them grow; and so, while we study, work, or play, the mending goes on, and we hardly stop to think that it is done at all. ”
