dazzling conversationalist right there's
nothing more satisfying than artfully
sharing your wisdom with friends and
family
and I've collected some of the most
amazing facts around so you can do just
that if you enjoy this video enough let
me know and I'll create some more to
make this the best series about amazing
facts on the web
why do you PS trucks always have their
doors open ever notice tell you PS
drivers always speed around in trucks
without any front doors on this unusual
practice is perfectly legal in America
and it all comes down to saving precious
time and money you see the average UPS
employee makes about a hundred and
thirty stops a day that's a lot of time
spent opening and closing doors
especially when some stops are just
minutes away from each other in business
terms more time always equals more money
so it makes financial sense for the
company to remove the doors altogether
instead
UPS trucks are also not fitted with AC
for the very same reason because getting
in and out of the truck multiple times
wouldn't make for a very efficient flow
of cold air as a result UPS drivers also
rely on the breeze blowing through their
door this vehicles to get some
much-needed respite from the scorching
summer heat
why don't you PS trucks turn left
generally speaking you'd be hard-pressed
to find a UPS truck making a left-hand
turn at a busy intersection and it's all
about that cold hard cash
when UPS decided to focus on greener
driving they fitted trucks with special
sensors and did some data mining to
discover that too many drivers were
idling while waiting to make a left turn
from 2004 onwards management instructed
drivers to turn right instead by
reworking pre-planned routes to minimize
the amount of necessary left turns ups
saw an immediate positive response to
this new clockwise system which amounted
to some three hundred and fifty thousand
more packages delivered annually around
10 million gallons less gas bird and
thirty-five million dollars saved what
is that tiny pocket on jeans there are
plenty of everyday things you have
probably never questioned the real
purpose of and I'll put that tiny pocket
at the front of your jeans is one of
them historically speaking this
seemingly useless addition to one of the
most popular clothing items was known as
a watch pocket this came about in the
1800s when Cowboys used to wear their
pocket watches on chains and their waste
coats until Levi's introduced the small
rectangular pocket which would keep the
watches from getting broken as times
change the pocket adopted various other
names each describing a new use
including ticket pocket coin pocket and
even condom pocket nowadays it's too
small to hold anything useful but it
remains as a staple of iconic fashion
history when was the least interesting
day in history it might think you've had
a dull day at work or school but can it
compare to what has been dubbed the most
boring day since the turn of the 20th
century according to the results of the
search engine true knowledge April
eleventh 1954 has been officially
bestowed with such a glowing title by
analyzing some 300 million facts about
newsworthy events a search engine was
able to identify that on this particular
Sunday in 1954 only two notable events
occurred a football player named Jack
shuffle bottom died and a Turkish
academic named Abdullah an alarm was
born
besides these events no real history was
made that day it has now surpassed April
30th 1930 which had previously been
considered the dullest day after a BBC
radio announcer declared there is no
news why can't pigs look up at the sky
pigs might be one of the most
surprisingly intelligent animals around
but they're also one of the only
creatures that are unable to look up and
see the sky although they could lay on
their backs or seat in a wandering
reflection pigs will never be able to
gaze at the sky like we do assembly
because their Anatomy does not allow it
their neck muscles are developed in such
a way that they can't raise their heads
enough to see the sky above them and it
comes down to evolution most animals
evolve in a way that optimizes escaping
predators and finding food and as a
pig's natural food like roots flowers
and insects are all down low there's no
need for such neck flexibility wear high
heels always for women high heels and
stilettos might be considered a feminine
accessory once upon a time this wasn't
the case back in the 10th century men
and horseback riding cultures in Europe
water heeled shoes which would make it
easier for them
stay in their stirrups the Persian
Calvary adopted inch high heels like
these and the trend then spread to
Europe as a signifier that someone owned
horses and was therefore wealthy
eventually upper-class women also began
wearing heels to assert their equality
and the shoes became a standard form of
dress for the wealthier members of
society throughout the 17th century by
the turn of the 19th century men had
renounced the high-heeled shoe is highly
impractical but women's heels had
already become more decorative and
fashionable so the custom continued why
can't you hold your nose at home humans
are capable of lots of things but
humming and holding our noses at the
same time is not one of them the simple
explanation is the same reason you can't
exhale while holding your nose and
closing your mouth because there's
nowhere for the air to escape from to
create a humming noise air must pass
through your larynx also known as your
voice box but it's impossible for this
to happen when your lips are tightly
sealed as a result you may be able to
hum for a couple of seconds but you'll
eventually have to open your mouth and
catch your breath go ahead try it
why can't newborn babies cry tears this
might come as a surprise after all most
babies come out screaming and crying
from the get-go but newborns can't
actually cry real tears this is because
we're not immediately born with
functioning tear ducts which usually
don't develop until we're somewhere
between two weeks and two months old
tears are produced by the almond-shaped
lacrimal glands under our eyelids they
come down over our eyes and the tear
ducts in the corners then act as a handy
drainage system to release them onto our
cheeks like a glass of water overflowing
scientists aren't really sure why the
system isn't placed straight away but
most babies definitely make up for it
once those ducts open up what is the
loneliest creature on earth in 1989 an
array of underwater hydrophones called
SOSUS which had been built by the Navy
to detect enemy submarines picked up
some unusual signals near the Pacific
coast
the sounds were familiar enough to be
classed as whale songs but they were at
a frequency of 52 Hertz which is
significantly higher than a blue whale
which sinks between ten to forty Hertz
or fin whales at around 20 Hertz a
marine mammal researcher named Bill
Watkins then decided to dead
his life's work to tracking this
solitary well which he nicknamed 52 by
the time Watkins passed away in 2004 he
had collected 12 years worth of
recordings of the unrequited mating
cause of this lonely whale whose voice
is simply too unique to attract a lover
researchers have never even seen the
well and can't be certain 252 still
wanders the sea today we're stop signs
always read road signs are well
established nowadays but once upon a
time the iconic bright red stop sign was
yellow instead the story goes that in
1922 the American Association of state
highway officials meant to determine a
standard design and settled on yellow as
their second choice by this time red was
already used on traffic lights partly
because the color had historically
signified danger but also because it is
scientifically classed as the color with
the longest wavelength the cone-shaped
cells in our eyes are tuned to detect
different wavelengths on the visible
light spectrum from 380 to 700
nanometers away and as red falls right
around 700 it is the color that can be
seen from farthest away sadly there was
no red dye in 1922 that wouldn't
eventually fade so they settled on
yellow which has the second longest
wavelength until fade resistant red
porcelain enamel became available in
1954 how many licks does it take to
reach the center of a Tootsie Pop this
age-old question has troubled anyone
with a sweet tooth and a taste for
Tootsie Pop since the candy launched the
iconic slogan and its commercials in
1970 although as the commercial states
the world may never know for sure
a few official tips have been made to
settle the debate once and for all
engineering students from Purdue
University designed a licking machine
which was built to function exactly like
a human tongue and found that it took an
average of 364 licks to reach the
tootsie roll center 20 human volunteers
also participated in the experiment the
old-fashioned way and averaged around
252 licks so I guess the real number is
somewhere between the two in other words
it takes too many licks than anyone
truly has time for unless you want your
tongue to end up like this how old is
the phrase oMG o M G which was
officially welcomed into the action
dictionary in 2011 is undoubtedly one of
the most widely used slang acronyms out
there besides lol but the origins of the
phrase are actually far older than you
might think in fact the earliest use can
be traced right back to a letter dated
from a British Navy admiral named John
Arbuthnot Fisher in 1917 and its
recipient was none other than Winston
Churchill himself Fisher famously wrote
I hear that a new order of knighthood is
on the tappets mg oh my god
shower it on the add morality if only
Fisher could foresee what will become of
the English language in the 21st century
wire chefs hats pleaded the classic
chefs had which is officially called a
toque Blanche is instantly recognizable
for its towering white shape but there's
more to this design than just fashion
origin stories vary from talk that chefs
were gifted special headgear in the 7th
century to placate them and at not
poisoning the King to one tale that
Henry the 8th ordered his chefs to wear
hats after he found a hair in his suit
by the time the toque Blanche had
reached it's recognizable design though
the pleats came to serve a subtle
purpose by signifying how much
experience a chef had in the early days
a chef with a hundred pleats might know
a hundred different ways to prepare eggs
or cook a chicken nowadays chefs hats
don't have so many pleats but a greater
number even if it's only three or four
still demonstrates their level of
experience why does one nostril get
blocked at a time one of the earliest
signs that you're coming down with a
common cold might be a stuffed-up nose
and usually one nostril feels
suspiciously more black than the other
this is thanks to a mind-blowing process
called the nasal cycle which happens
constantly but only becomes apparent
when you're sick you may never notice
but you're always breathing more heavily
from one nostril than the other because
they switch sides throughout the day the
body inflates tissue with blood to open
one side of your nose and partly closed
the other every three to six hours so
that they work in regular shifts this
system is thought to round out our sense
of smell because some smells are better
picked up by fast flowing air through
the nose while others are detected with
slow-moving air a constant stream of air
through both nostrils would also dry out
and kill the tiny hairs which protect us
from foreign contaminants this subtle
process is ample
when you're sick because the nostril
that is effectively turned off feels way
more clogged than the other
how was Nutella invented Nutella is one
of the world's favorite spreads which
can now be found in many shapes and
forms but its beginnings are far humbler
than you might imagine
although the first jar of Nutella left
the factory on April 20th 1964 its
origins can be traced back to the 1940s
during World War two an Italian pastry
maker named Pietro Ferrero decided to
mix a sweet paste he'd made from
hazelnuts with a small amount of
precious cocoa to make his chocolate
ration last as long as possible his
popular creation named gianduja after a
famous local carnival character at the
time was then packaged in the form of a
small loaf and sold in slices
legend has it on one hot summer in 1949
the same year Pietro died the gianduja
product melted in a warehouse in Alva so
his son Michele packaged and sold it in
jars instead after being branded nutella
in 1962 the spread slowly gained its
legendary status and it was a series of
accidental coincidences that started it
all so do you want this format of video
turned into a series if so let me know
in the comments below and I might just
do it also make sure to let me know down
in the comments which of these
interesting facts wowed you the most and
