Since Antiquity,
yawning has held as little interest for
philosophers, psychologists and
physiologists, as it has for teachers,
moralists and physicians. And yet, few things
are as common as yawning. Everyone yawns 5 to
10 times a day. Yawning is a recognized
behaviour in almost all vertebrates from
birds to humans, one which starts in the womb
and continues until death. Although yawning
often procures a sense of well-being for the
yawner, attempting to mask this behaviour is
worldwild usual practice.
