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.
