The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Expression of Emotion in Man and Animals by Charles Darwin: of force somewhere;" so that, when the cerebro-spinal system is
highly excited and nerve-force is liberated in excess, it may be
expended in intense sensations, active thought, violent movements,
or increased activity of the glands.[7] Mr. Spencer further maintains
that an "overflow of nerve-force, undirected by any motive,
will manifestly take the most habitual routes; and, if these do
not suffice, will next overflow into the less habitual ones."
Consequently the facial and respiratory muscles, which are
the most used, will be apt to be first brought into action;
then those of the upper extremities, next those of the lower,
and finally those of the whole body.[8]
