  • Hey there and welcome to Life Noggin.

  • Death is a sad, yet inevitable part of life.

  • At some point, you will die and there is some weird, kinda creepy stuff that starts to happen to your body.

  • First off, after you die, your body will start to get cold.

  • In fact, every hour after you die, your body will get about 0.8 degrees Celsius cooler

  • until it reaches room temperature.

  • And meanwhile, your cells will start dying from a lack of oxygen,

  • since ya know, your lungs are no longer working and your heart has stopped beating.

  • But this lack of oxygen won't kill them right away...instead, they will live for several minutes.

  • And during this time, there are still chemical reaction occurring that produce carbon dioxide

  • and increase the acidity of the cell.

  • Enzymes in the cells then start to digest the cell membrane, causing the cell to break down and start leaking.

  • And the enzymes that escape can go on and break down the other cells around it.

  • Creepy, huh?

  • And fun fact: when your muscles relax after you die, it may lead to you peeing or defecating if you hadn't used the bathroom in a while.

  • Anyway Later on, blood starts to spill out from broken blood vessels

  • and since it isn't flowing around your body, you will start to look pale.

  • Now, if you are lying down, as you probably will be, the blood will begin to travel down thanks to gravity,

  • and will be settle in the lowest regions along your back side.

  • And this will eventually lead to discoloration.

  • About two to six hours after death, rigor mortis kicks in.

  • When you are living, you are able to contract and relax your muscles at will.

  • But with rigor mortis, after your cells have used up the last of their energy supply,

  • the protein filaments allowing your muscles to move become locked in place,

  • which is why dead bodies are so stiff.

  • And this stiffness usually lasts for about three days.

  • A few days after death, putrefaction begins as the bacteria in your gastrointestinal tract will start to break down tissues and cells,

  • liquefying your body and producing horrific-smelling gases like methane and hydrogen sulfide.

  • And with the production of gas comes the bloating of your belly.

  • The gas pressure causes any liquids in cells and blood vessels to spill out,

  • which may eventually start to leak out of your body.

  • And sometimes the pressure is so great that the abdomen bursts open,

  • which is definitely an image that will haunt my dreams forever.

  • Thank you for animating that okay?

  • And since your body is smelly, it will attract blowflies that will lay eggs in your rotting flesh,

  • leading to the birth of maggots within a day.

  • These maggots feed on your flesh, attracting beetles and other insects.

  • Boy this is a beautiful episode!

  • 20 to 50 days after death, a process called butyric fermentation begins as the flesh is removed and your body dries out.

  • And the parts of the body touching the ground start to develop mold.

  • Then, over the course of years, all your flesh has been decomposed and eaten by various insects and animals

  • and all that is left of you is your skeleton.

  • So it's not a pretty process at all and it sure doesn't smell nice,

  • but it sure makes me happy that most of the time someone dies, their body is quickly disposed of

  • so no one has to witness all of that.

  • But hey, at least the science is interesting, right?

  • Death may seem scary but sometimes it's fascinating.

  • Head over to our friend, Rob Dyke's channel to learn more.

  • Thank you for living and don't forget to leave your suggestions for future videos in the comment section below.

  • We're gonna be making more of them people!

  • Make sure you come back every Monday for a brand new video.

  • As always, I'm Blocko and this has been Life Noggin.

  • Don't forget to keep on thinking!

Hey there and welcome to Life Noggin.
