Our newest merch drop is here, and this time it's all about improving your sleep.

Head over to the Kotzkzak shop, and now, snuggle up.

The video is starting.

Your heart beats one last time, jerks a bit, and then nothing.

Your blood goes from roughly 5 kilometers an hour to a full stop.

for a split second nothing changes your body is still buzzing with activity you're awake

and alert your lungs are still filling up and your chest is rising

but it will only take seconds for the cascade of death

to begin what does this actually mean death is not a switch not a single moment no sudden transition

you're a complex self -organizing society of 30 trillion individual cells.

Death is a complex sequence of irreversible events that slowly make you merge with the grander universe again.

Let's die together and witness what exactly happens to your body as you shut down.

What does it actually mean to die?

In a sense, death is all about a lack of oxygen, a chemical knife

that animal cells use to split sugar molecules to gain the

currency of life chemical energy bound in atp your cells each combine millions of sugar

and oxygen molecules each second

so your body is built around constantly pulling oxygen from the air loading it into your blood

and distributing it to every cell of your body this process is so crucial

that over 80 percent of your cells are exclusively devoted to

carrying oxygen in an iron cage your red blood cells

and this is why the death cascade usually begins with your brain heart

or lungs if your lungs fail oxygen can't be harvested

if your heart fails it can't be distributed and

if your brain fails neither can continue working wherever death starts

your brain is usually the first part of your body

that dies it's your most oxygen

and energy hungry organ running quadrillions of operations each second less

than 30 seconds after your heart stops the electrical communication between the different parts of your brain begins to fade

you think your last conscious thought and faint that's it silence just you

and a question did i make the most of my life did i make a difference in our story

And now, back to your dying brain.

Neurons are biological electrical wires with almost no sugar storage and especially vulnerable to a lack of energy.

Like all cells, they're bags of molecules and water separated by a delicate membrane from their surroundings.

This membrane is an extremely active, high -tech molecular machine, constantly monitoring and guiding millions of molecules inside and outside,

maintaining a fragile balance, which needs loads of energy.

As soon as a neuron gets low on energy, it starts shutting down non -essential processes.

But as its reserves run out, the membrane stops working and the outside invades.

Water and salt ions begin to diffuse in, causing the cell to swell.

This is bad.

Neurons membranes actively balance out different ions to maintain a potential of literal electricity that they use to send and receive orders.

When too many ions rush in, the electrical balance collapses, the neuron goes dark.

As the membrane fails, the neuron spills ions onto its neighbors, causing their electricity to fail, and they go dark too

but it gets even worse the dysfunctional membrane starts absorbing massive

amounts of the most dangerous iron of all calcium useful in small doses

it now turns into a killer inside the neuron it activates enzymes

that break down vital cellular structures damaging it beyond repair the failing cell goes into panic mode

and vomits neurotransmitters onto its neighbors they have a double effect

They scream at other neurons to get more excited, forcing them into electrical overdrive, speeding up their eventual collapse.

And they order them to take up even more calcium.

Normally, this is part of their regular signaling, but now it only makes things worse.

A deadly chain reaction is unleashed.

Dying neurons destabilize their neighbors, spreading electrical failure and death.

A slowed tsunami of death is spreading through your brain at the speed of a few millimeters per minute.

Are you experiencing anything in this phase?

Maybe.

There are reports of near -death experiences, and your brain is certainly flooded with chemicals that create a final surge of desperate activity.

But it's hard to tell because in this moment your memories, dreams and identity are erased from the universe,

as the structure that made you you is starting to turn into a gooey liquid mush.

Will you go on to exist in some other way? well

maybe the truth is nobody knows anything for sure in less

than 20 minutes your brain is irreversibly lost no more signals

and orders arrive anywhere else in the body now each organ

and tissue is left on its own without central coordination many societies

and legal systems treat this as your death at this point you can still save a few lives

if you're an organ donor but the rest of your body is on a tight timer.

The death cascade continues on.

The end of your heavy machinery.

The blackout spreads to your heavy industry.

Organs that perform continuous, demanding work like your liver, kidneys and your stopped heart go into survival mode.

They have one key advantage over the brain, large reserves of sugar and an emergency generator.

The chemistry is complicated, but in a nutshell, they can get energy from sugar without oxygen.

Though way less efficient, it buys them up to an hour of precious time.

As your organs' cells switch from regular breathing to the emergency generator, some of their genes ramp up their activity,

activating machinery to respond to stress and repair damage to survive as long as they can.

But for many of your cells, the stress becomes too great.

They use the emergency system to destroy themselves in a quiet, orderly way.

For the cells still trying to hold on, the emergency energy comes at a huge cost.

Without oxygen, sugar is broken down incompletely and turns into lactic acid that degenerates their insides.

Eventually, either their energy reserves run out or too much acid accumulates and their internal machinery breaks.

Some are tiny sacks of digestive enzymes that dissolve anything organic.

As these sacs break open, the cells dissolve in a corrosive mix of acids and rogue enzymes.

Their membranes break down, the cells swell up with water and burst,

100

showering their neighbors with the same deadly mix of chemicals that killed them from the inside.

101

At the same time, the severe energy depletion has reached your muscles.

102

Paradoxically, they can't relax anymore.

103

The fibers within them need energy to let each other go, and now they lock up.

104

Starting in your eyelids, jaw and neck, a wave of stiffening works its way through your body, turning meat to stone.

105

Even the tiny muscles around your hair follicles lock up, giving you your final goosebumps.

106

Your most important muscle, your heart, is forced to slowly contract one final time.

107

A sad echo of your heartbeat as your blood turns deeply acidic.

108

Which leads us to the third and creepiest act of this drama.

109

Your necrobiome emerges.

110

Your body, mostly your gut, hosts roughly 30 trillion bacteria.

111

Friendly symbionts that break down fibers, produce vitamins, or keep hostile bacteria in check.

112

But they're not actually your friends.

113

All these microbes are strictly confined behind the gut lining, held off by physical wool and immune cells.

114

But an hour after your heart stopped, this border is crumbling.

115

Your body is carbs, fats, and proteins.

116

food first millions then billions break out of your intestines through the apocalyptic highways of your lymphatic system

117

and acid -filled blood vessels your microbiome turns into your necrobiome

118

but hold on there's still resistance within your body the last

119

remnants of your immune system are desperately fighting back built to thrive in the most extreme oxygen -starved regions of your body,

120

your immune cells survive long after you've stopped breathing they don't need a complicated organ structure

121

or orders to work even when the body is dying around them

122

so in a final attempt to save you they fight

123

without blood flowing their communication with each other is lost their

124

once mighty army is scattered across your giant body soldiers call for backup

125

and for help but their signals don't travel and

126

so they fight a lonely last stand micro battles imperceptible even just a millimeter away

127

until their exhausted little bodies can't go on anymore after 24 hours your last immune cell finally dies

128

there's also no happy ending for most of your thriving necrobiome

129

for most of these bacteria the outside's oxygen is toxic by dissolving your body

130

they're working towards their own end without knowing it the death paradox

131

but even in this barren landscape of your blood

132

and organs a few final holdouts remain microscopic glimpses of life

133

your red blood cells have shriveled up like sickly purple raisins

134

but the most sturdy ones survive up to a day

135

or two and like puddles in a drying lake pockets of cells here

136

and there are still alive in the outer suburbs your skin

137

and some connective tissues never needed much energy in the first

138

place your genes were built over billions of years of evolution to keep you alive

139

and the news of your death has not reached all of

140

them yet many cells are still translating your dna into the

141

building blocks of your past life long after your death gene activity in your blood

142

and organs rises and falls in coordinated patterns frantically trying to activate stress responses

143

and repair you some of those genes will remain active for days

144

and finally deep within your muscles

145

and bone marrow stem cells trigger a survival program slowing down their metabolism

146

and entering a sort of deep sleep just for the tiniest chance

147

that there'll be a time to rebuild your body

148

it will take weeks for the last of these survivors of a fallen planet to die

149

at this point all of you is completely dead but

150

when did you die

151

when your heart stopped your brain died your final defense is collapsed we can measure

152

when organs fail when neurons fall silent when the body stops

153

but life is more than the sum of its parts and

154

so the death of you the exact moment you disappear remains a mystery

155

we know a topic like this might cost you a good night's sleep

156

but we want to make it up to you with our new sleep collection it's not only science inspired

157

but also extremely cozy get comfy and relax

162
