Death sucks!
-
But what happens to your body
after you die is fascinating.
-
So we're going to show you.
-
Don't worry, it won't be gross...much.
-
Once a person's breathing stops,
-
the cells in their body
stop receiving oxygen,
-
but the cells continue to live
for several minutes
-
generating carbon dioxide.
-
Carbon dioxide is acidic,
-
and it builds up,
rupturing sacs inside the cells.
-
These sacs contain enzymes
-
that begin to digest the cells
from the inside out.
-
This creates a blister-like fluid
rich in nutrients.
-
After about a week, those nutrients
-
fuel an army of bacteria and fungi
-
that further liquefy organs and muscles.
-
The microbes that attack the tissue
-
produce a bewildering array of
more than 400 chemicals and gases.
-
They include freon.
-
That's right, the coolant found in refrigerators.
-
Benzene, a powerful component in gasoline.
-
Sulfur, which smells
of swamps and rotten eggs.
-
And the molecule known
as Carbon Tetrachloride,
-
which was used in fire extinguishers
and dry cleaning
-
until scientists discovered
it's highly toxic.
-
At this point,
there's very little flesh left,
-
and it's consumed by... here it comes...
-
maggots and beetles.
-
Insects leave only bones behind.
-
Over time, the protein
in bone decomposes too,
-
leaving just the bone mineral
called hydroxyapatite,
-
which eventually turns to dust.
-
We can take some solace in the fact
-
that all those nutrients and chemicals,
even the dust,
-
provide vital substances
that make soils fertile,
-
sprouting plants and other new life
-
after our lives have ended.
-
Ashes to ashes, dust to dust.
