A positive cue to watch for in your interactions with others are what are called `gravity defying` behaviours, where the body is unconsciously moved in a motion upwards... against gravity.
For example, raising the toe upward
while standing (while the heel remains on the floor) is generally a sign that
the person is feeling positively disposed toward what is being said. This type
of behaviour is rarely seen with clinically depressed individuals.
are excited and interested you tend to see more gravity defying behaviours.
Just another little cue to keep in mind when `selling` someone, whether a
product or even on an idea!
