I added these fun facts to the Vitruvian man slide:
= = Stacy = = =Annie's Extras=
 * a [|palm] is the width of four fingers
 * a [|foot] is the width of four palms (i.e., 12 inches)
 * a [|cubit] is the width of six palms
 * a [|pace] is four cubits
 * a man's height is four cubits (and thus 24 palms)
 * the length of a man's outspread arms (arm span) is equal to his height
 * the distance from the hairline to the bottom of the chin is one-tenth of a man's height
 * the distance from the top of the head to the bottom of the chin is one-eighth of a man's height
 * the distance from the bottom of the neck to the hairline is one-sixth of a man's height
 * the maximum width of the shoulders is a quarter of a man's height
 * the distance from the middle of the chest to the top of the head is a quarter of a man's height
 * the distance from the elbow to the tip of the hand is a quarter of a man's height
 * the distance from the elbow to the armpit is one-eighth of a man's height
 * the length of the hand is one-tenth of a man's height
 * the distance from the bottom of the chin to the nose is one-third of the length of the head
 * the distance from the hairline to the eyebrows is one-third of the length of the face
 * the length of the ear is one-third of the length of the face
 * the length of a man's foot is one-sixth of his heigh
