WHY DO PEOPLE CRY?

Crying, or lachrymation, is the process of producing tears,
which in human eyes are produced by glands under the
eyelids People cry for a number of reasons: basal tears are
continually produced to lubricate and clean the eyes, while
reflex tears wash away irritants and foreign particles However,
a third type of tears, emotional tears, are produced
when a person cries
When a person is hurt, physically or emotionally, the lachrymal
glands sometimes constrict and produce emotional
tears When a person is in an emotionally overwrought state,
the body overreacts and produces a flood of hormones and
other chemicals found to be
present in emotional tears
and yet absent in basal and
reflex tears Current thinking
has it that crying is beneficial
to the body’s physical
and emotional health, as it
helps the body to dispose of
these additional stress hormones and chemical toxins and is
why people often feel better and calmer after a good cry Indeed,
this view is now supported by scientific research Even
the philosopher Aristotle believed that crying cleansed the
mind of suppressed emotions
Humans are the only animals to cry (although some suggest
that gorillas and elephants might, too), largely—it is
believed—due to their heightened sense of self-awareness

WHY ARE PEOPLE’S EYES DIFFERENT COLORS?

    The colored part of the human eye, surrounding the black
    pupil, is called the iris, a word deriving from the personification
    of the rainbow in Greek mythology The color of the iris
    is usually brown, blue, green or hazel
    The color of the iris is provided by a pigment called melanin,
    which is also present in the body’s hair and skin, although
    this is of a slightly different type The melanin in the
    iris is yellow-brown to dark brown in color, and the amount
    of melanin in a person’s irises will determine their eye color—
    for instance, a person with a high level of melanin will
    have brown eyes, while someone with less melanin in their
    irises will have blue eyes People whose skin and hair are
    dark tend to have more melanin and darker eyes than people
    whose skin and hair are fair
    It was originally thought that eye color was determined
   by one specific gene, but it is now believed that a number
   of genes are involved The genes that cause brown eyes are
   dominant, so, if one parent has brown eyes and the other
   parent has blue eyes, the child is more likely (though not
   certain) to have brown eyes It is, however, possible for a
   brown-eyed parent to produce a child with blue eyes if the
   parent’s eye color is the result of carrying recessive blue-eyed
   genes as well as the dominant brown-eyed genes In addition,
   some blue-eyed babies’ eyes darken as their levels of
   melanin increase with age.
   It is possible, although rare, for a person to have different
   levels of melanin in each eye, a condition called heterochromia
   iridium, which results in each eye being a different
   color This condition can be inherited or can result from an
   alteration of one of the relevant genes Alexander the Great
   had this condition A similar condition, heterochromia
   iridis, manifests itself as a variety of colors within one eye.

HOW DID THE WORD “SHIT” ORIGINATE?

  It is claimed by some that the word “shit” originates in the
  sixteenth century, when manure was transported by ship
  The dry manure weighed little and was stowed below deck
  When mixed with water, however, it gained in weight and
  began to ferment, producing methane gas, which, when
  exposed to a naked flame (that of a lantern, for instance),
  would ignite, causing explosions and fires Because of these
  accidents, crates of manure were labeled “Ship High in
  Transit” to indicate that the crates were to be stowed above
  the deck, so that any water that the ship took on would
  not come into contact with
  them It was assumed by
  many that the word shit was
 an acronym derived from
 this labeling convention
 However, this theory has
 since been discovered to be a
 complete falsehood that can be traced to an Internet posting
 in 1999 and that has been perpetuated ever since The word
 shit is from the Middle English word “shitten,” which in turn
 derived from the Old English word “scitan,” from
 which meant “to be covered with excrement” and is in turn
 thought to originate from the Indo-European root
 word can also be traced back to Germanic languages at the
 time of the Roman Empire The word “shite,” meanwhile, is
 a variant form of the word that is found in some dialects in
 Ireland and Scotland, as well as in colloquial English.

DO WE REALLY USE ONLY 10 PERCENT OF OUR BRAINS?

Psychologists in the early twentieth century commented
that humans use only 10 percent of their brains, and Albert
Einstein also indicated that humans use only a small portion
of the brain It’s a theory that has been propounded in television
documentaries, magazines, advertisements and books
over the past century Psychics have also latched on to it as
a possible explanation for paranormal behavior, attributing
unusual incidents to the workings of the unused portion of
the brain They profess that 90 percent of the brain consists
of untapped potential that is capable of remarkable feats
Nearly all scientists now agree that the theory that we
use only 10 percent of our total brain function is completely
unfounded In fact, they question how this figure
was arrived at in the first place and what areas of the brain
are supposed to be redundant The theory supposes that if
90 percent of the brain were removed, a person would still
be able to function normally, whereas in reality it is known
that damage to even a small area of the brain can result in
physical devastation
In addition, most significant disorders of the brain
involve only a small and very specific area of the brain If
the 10 percent argument was true, it’s unlikely that so many
problems would persistently occur in that area And if we
use only 10 percent of our nerves and neurons in the brain,
how would this be measured? Indeed, imaging of the brain
in scans shows that all parts of the brain are used for different
activities and that many areas of the brain are used for
some complex activities or thought processes Throughout
the course of one day, most areas of the brain are active at
some time, even during sleep The 10 percent theory suggests
that a discrete area of the brain is not used, whereas
scans reveal activity throughout the entire brain and not in
any isolated segment The final nail in the 10 percent theory
is the fact that neurosurgeons carefully map the brain before
removing tumors so that they don’t compromise other
essential areas
From an evolutionary perspective, it’s highly unlikely
that our comparatively larger brains would have evolved
from our ancestors if the extra areas were surplus to requirements
In fact, there is absolutely no evidence to support the
10 percent theory.
