Breathing and us

Breathing is a fundamental behavioral manifestation of the psycho-
logical and physiological state of human beings, from the breath that marks
the beginning of life to the breath that marks the end. Vocalizations that
range from the rudimentary reflexive cries of the distressed infant to the
sophisticated speech of a persuasive orator depend on breathing maneuvers
reinforced by their effects. Similarly, the frequency and intensity of the
sighs and gasps and grunts and groans and cries and shrieks and titters
and laughter that mark the oral language of everyday discourse, and convey
a part of the emotional message that underlies the denotative meaning of
our words, are rooted in breathing.
