• From why you have a belly button to where hiccups come from, we answer 10 of your most
burning questions about the human body • Hey there, my name is Shima, I'll be reading
out the questions and answers • I'm Danger Dolan and I'm here to blow
your mind with truth 10 – Why do I have a belly button?
, • When you get older, you’ll be hiding
things inside your belly button to sneak through airports – usually deodorant, toilet paper
and bottles of water – don’t try to hide one of your friends in there though, security
can always tell • The belly button is where the umbilical
cord, the tube that connected a baby to their mother, used to be to give the baby food and
oxygen to live.
After a baby is born, the cord is cut and eventually turns into a belly button!
9 – Where does blood come from?
, • The more important questions is: where
do teachers get the ink for their red pens?
And what happened to that kid who kept getting detention but one day did something so bad
that he never came back?
Pay attention in class, or one day you might find a little note from your teacher, and
she’ll let you know EXACTLY where blood comes from
• Blood carries oxygen and nutrients all over the body and is made up of red cells,
white cells, and plasma.
Plasma is mostly water but the red and white cells are made in the marrow of bones, the
liver, spleen, and parts of the body called the thymus gland and lymph nodes.
8 – What's a “Funny Bone?”
, • This is the part of your body that makes
you laugh when someone tells a really good joke, you also use when to replying to a funny
message from one of your friends L-O-L, I AM LITERALLY ON THE GROUND LAUGHING,
HA – HA, THAT ROFLS MY WAFFLES • That weird feeling when you hit your elbow
is why it's called a “funny bone,” but it's not a bone at all!
It's actually a nerve called the ulnar nerve—it controls the feeling in your 4th and 5th fingers
and also helps to control the movement in your wrist.
7 – What are “butterflies in your stomach?”
, • It’s an alarm system in your body that
lets you know that girl you kinda sorta maybe like a little bit is actually a demonic soul
wrenching alien wearing a mask, and that you should let that legendary hero disguised as
the cool kid ask her out to the movies before you do – to protect you, of course
• Butterflies in the stomach are just nervous, fluttery feelings you might feel before a
big test or before talking in front a large group of people.
These feelings in your tummy are perfectly normal and some people even believe that they
actually make you perform better by keeping you on your toes.
6 – What causes hiccups?
, • Every hiccup you do means you’ve lost
one day of your life, so if you hiccup regularly it means you don’t have much longer on this
world, so you should do squats to make your number of days left go back up again – it’s
just that easy • Hiccups come from when the diaphragm,
the muscle that controls your breathing, becomes irritated and moves jerkily, like after eating
too much or too fast.
The sudden rush of air hits your voice box and results in a hiccup.
5 – Why do people need sleep?
, • It’s for the same reason why you brush
your teeth – if you don’t sleep, your brain will get covered by plaque, turn yellow
and eventually rot away until there’s nothing left, then you’ll have to get a fake brain
put in just to work out what 2 + 2 is • Sleep is vital for your body in order
to rest and allow for it to prepare for the next day.
During this time, your brain replaces chemicals, sorts and stores information from the day,
and solves problems.
Without sleep, you'll become clumsy and cranky or even get sick!
4 – Why do we need to breathe air to live?
, • Pfft, only nooblets breathe air – are
you a NOOBLET?
Real men develop GILLS on the side of their neck in order to breathe fire, UNDERWATER
– in SPAACE *crazy breathing noises* • Put simply, our bodies need oxygen.
By breathing air, our bodies can take in oxygen which in turn is used to create energy inside
our bodies.
Without this energy, our bodies just wouldn't work!
3 – Why do I get a headache when I eat ice cream too quickly?
, • You shouldn’t be getting a headache
at all – the ice cream should make your throat freeze up, but if your brain’s getting
sore it means you might need experimental electro-shock brain surgery like I did – but
don’t worry man, everything will turn…
out… okaaaar….eerrrr…
• When you eat something cold too fast, the blood vessels in your mouth, neck, and
head work to keep you warm by shrinking so that less blood is sent to those body parts.
This and the rush of sugar, combine to give that familiar “ice cream headache” or
“brain freeze!”
2 – If you are colour-blind, does that mean you see things in black and white?
, • No, this is a common mistake – being
colour-blind just means you can’t appreciate art, like this masterpiece I whipped up earlier
– I call it, the APPLE…
I think… or was it… the STRAWBERRY… definitely a fruit… or it might be a basketball?
Wait… where am I?
• Being colour-blind doesn't mean you see everything in black and white.
It just means that you may be missing particular colour cones, the little parts in your eye
that let you see colour.
This just means there are some colours you can't see, but everything else is fine.
1 – Is it ever possible to drink too much water?
• Yes, if you drink too much water you’ll become pale, always covered in sweat, your
hands cold and slimy – I had a friend who was like this once, but one day I went over
to his house, he was gone, there were empty water bottles everywhere and a frog just laying
there – then I heard the frog croak: “Dolan, it’s me”
• In most cases, the answer would be no.
In rare cases however, it is possible to consume too much water.
A person with an unusual illness called psychological polydipsia can drink unhealthy amounts of
water, but this comes from their illness rather than from needing water.
