HAPPY

Referring now to the same people smiling, it is re-markable how similar the facial reactions are in two very different people — the heavy crinkling under and at the corners of the eyes and the deepening of the naso-labial furrows. Another furrow appears on both, running from below the chin, up the cheek. This can be seen in an extreme form in Fig. 64. It should be elear from these pictures that the common practice of cutting lines in the face with a 'V' tool is totally inadequate and inappropriate. These folds are either soft and smooth or deep with sharply rounded edges. Nowhere is there a 'V'. One could conceiv-ably use it for the creases on the man's forehead but the edges would have to be rounded.

The muscles radiating from the mouth are con-tracting and pul ling the lips upwards and baekwards. There is also some contraction of the circular muscle round the eye. This clearly demonstrates the folding of the skin created at right angles to the direction of the muscle contraction.
