What happens to your body after 100 years in a coffin

Trying to think about staying alive can be hard enough, but what about you when you die?
We’re not talking about afterlife type stuff here. We want to know what physically happens to your body and what would be left of it after 100 years in a coffin.
Well, according to Business Insider, things are starting to go rather westward well before a century.
Your body contains over 200 bones, a few trillion microbes, up to 37 trillion cells, and it doesn’t take long before they start to break down.
Disgusted people might want to stop reading now. You see, a few minutes after death, one of the first things to do is your brain.
Your heart stops blood flow when it stops beating, which is important because it is the blood that carries oxygen to your organs and tissues. Without it, the organs that need oxygen the most will starve first.
As a result, these cells begin to leak fluid.
You know, we are constantly told that we are 70% water? Well, it has to come out somewhere, and without oxygen to keep them alive, it’s the cells in places like the brain that self-destruct first, soaking the coffin floor in the process.
Within the first 24 hours of being in a coffin, your gut will be the next to start breaking down. Because your immune system is dying, it can’t contain the trillions of starving microbes that, when you were alive, would help digest your food so you can eat it.
They escape from the lower intestines through tissues, veins and arteries. Then they reach your liver and gallbladder, which contain yellow-green bile that used to break down fat when you were alive.
The microbes will however eat the liver and gallbladder, which means that the bile will start to flood the body, making it yellow-green.

These microbes then dominate on the second to fourth day, producing toxic gases such as ammonia and hydrogen sulfide. These will cause your body to swell and smell terrible as well.
Fast forward three to four months and you’re no longer yellow-green! But you are now a brownish black because your blood vessels have deteriorated causing the iron inside them to spill and oxidize.
Another pleasant thing that happens at this point is that the molecular structures that hold your cells together break down, which means your tissues are collapsing into a watery slurry.
Any cotton clothing you may have worn will disintegrate about a year after entering the coffin, broken down by the acidic bodily fluids which, as we have explained, have been leaking for quite some time now.
It then calms down a bit, but after a decade or so the humid, barely oxygenated environment causes a chemical reaction that means the fat in your thighs and behind turns into a soap-like substance called serious wax.
However, if your casket was buried in drier conditions or if your bodily fluids weren’t causing too much moisture, you might start to mummify.
This is caused by the evaporation of water through the thin skin of your ears, nose, and eyelids, causing them to dry out and turn black.
By age 50, your tissues will have liquefied and disappeared, leaving the skin and tendons mummified. These also disintegrate.
By age 80, your bones will have cracked because the soft collagen inside them will have deteriorated. You will be reduced to your skeleton, but not for very long.
For after 100 years the last of your bones will have turned to dust. In fact, only the teeth will be left, as they are the most durable part of your body.
So this is it. Enjoy your lunch.
