" A recent invention, vocal language may date back only ca. 200,000 years. As human primates, we have not fully come to grips with the prolonged, face-to-face closeness required for speech. Speaking to a stranger, e.g., stresses our autonomic nervous system's sympathetic (i.e., fight-or-flight) division, which a. speeds our heartbeat, b. dilates our pupils, and c. cools and moistens our hands. The limbic brain's hypothalamus instructs the pituitary gland to release hormones into the circulatory system, arousing our blood, sweat, and fears. "

" Feedback smile. Smiling itself produces a weak feeling of happiness. The facial feedback hypothesis proposes that ". . . involuntary facial movements provide sufficient peripheral information to drive emotional experience" (Bernstein et al. 2000). According to Davis and Palladino (2000), ". . . feedback from facial expression [e.g., smiling or frowning] affects emotional expression and behavior." In one study, e.g., participants were instructed to hold a pencil in their mouths, either between their lips or between their teeth. The latter, who were able to smile, rated cartoons funnier than did the former, who could not smile (Davis and Palladino 2000). "

" Supermarket mandatory smile. In the late 1990s, Safeway, the second largest supermarket chain in the U.S., instructed its store employees to smile and greet customers with direct eye contact. In 1998, USA Today ("Safeway's Mandatory Smiles Pose Danger, Workers Say") reported that 12 female employees had filed grievances over the chain's smile-and-eye-contact policy, after numerous male customers reportedly had propositioned them for dates. Commenting on the grievances, a Safeway official stated, "We don't see it [the males' sexual overtures] as a direct result of our initiative. "

" The two-point rhythm of walking's stride clears the mind for thinking. (N.B.: Perhaps, after telling the spinal circuits to "take a walk," the forebrain shifts to automatic pilot, so to speak, freeing the neocortex to ponder important issues of the day.) Many philosophers were lifetime walkers, who found that bipedal rhythms facilitated creative contemplation and thought. In his short life, e.g., Henry David Thoreau walked an estimated 250,000 miles--ten times the circumference of earth. "

" Our face is exquisitely expressive. Its features are incredibly mobile, more so than any other primate's. Because our face "speaks for itself" with muscular eloquence and candor, speech has comparatively few words (such as, e.g., "smile," "pout," or "frown") for its diverse gestures (see, e.g., TENSE-MOUTH and TONGUE-SHOW, which lack dictionary entries). Emotionally, the face is mightier than the word. "
