What happens to our bodies after we die? – Farnaz Khatibi Jafari

Since the dawn of humanity, an estimated 100.8 billion
people have lived and died, a number that increases by about
.8% of the world’s population each year. What happens to all
of those people’s bodies after they die and will the planet eventually
run out of burial space? When a person’s heart stops beating, the body passes through several
stages before it begins decomposing. Within minutes after death, the blood begins settling in
the lower-most parts of the body. Usually eight to twelve hours later, the skin in those areas is discolored
by livor mortis, or post-mortem stain. And while at the moment of death
the body’s muscles relax completely in a condition called primary flaccidity, they stiffen about two to six hours later
in what’s known as rigor mortis. This stiffening spreads
through the muscles, and its speed can be affected by age,
gender, and the surrounding environment. The body also changes temperature, usually cooling off
to match its environment. Next comes decomposition, the process by which bacteria and insects
break apart the body. Many factors affect
the rate of decomposition. There is, however, a basic guide of the
effect of the environment on decompositon called Casper’s Law. It says that if all other
factors are equal, a body exposed to air decomposes twice
as fast as one immersed in water and eight times as fast
as one buried in earth. Soil acidity also greatly
affects bone preservation. High-acidity soils with
a pH of less than 5.3 will rapidly decompose bone, whereas in a neutral or basic soil
with a pH of 7 or more, a skeleton can remain in relatively
good condition for centuries. Different cultures throughout history have
developed unique approaches to burials. As far back as
the first Neanderthal burials, death was accompanied by rituals, like the positioning, coloring,
or decorating of corpses. Traditional Christian burials decorate
the body in dress, while in traditional Islam, a body is wrapped in a piece
of ritual fabric with the face oriented toward Mecca. Traditional Hindus ceremonially burn
the body, and Zoroastrians, followers of one of the
oldest monotheistic religions, traditionally place bodies atop a tower
to expose them to the Sun and scavenging birds.` Before the Industrial Revolution,
burials were simple and accessible. These days, with suitable burial land
running out in high-population areas, purchasing private gravesites
can be costly, and many people can’t afford
simple burials. Even cremation, the second most common
burial practice in the world, comes with a high cost. As for the question
of running out of space, the issue isn’t so much about total land
in the world as it is that large populations cluster
together within cities. Most of the big cities in the world may run out of suitable burial grounds
within a century. For London, it’s even sooner. That may happen by 2035. So are there alternatives
to traditional burials that might help with the space issue? In some countries, skyscraper cemeteries
enable vertical burials. Some options focus on the body’s
relationship with the environment. Promession, for example, freeze-dries
and pulverizes the body, creating a powder
that can turn into compost when mixed with oxygen and water. There are also green burials that use
special materials, such as biodegradable caskets, urns that sprout trees, and burial suits that grow mushrooms. Eternal reefs take that concept
to the depths of the ocean using a mixture of ashes and cement
to create marine habitats for sea life. Death is an inevitable part
of the human condition, but how we treat bodies and burials
continues to evolve. We may each have different spiritual, religious, or practical approaches to dying, but the ever-increasing demand
for burial space might give us a push to be creative about where our bodies go
after the final stages of life.

    You actually get confused when you think about how life started, how the universe came into being and the like. So leave it.

    After we die
    We’ll see Lord Jesus Christ who is the only the way to be saved
    But we the Him or as a Savior and Redeemer and enter everlasting life
    Or see Him as a judge and enter everlasting dead!
    So… repent and change your mind and life until it’s not to late
    Kingdom of Heaven is at Hand!
    Read Bible!

  26. Studio ELB May 7, 2019 at 3:49 am

    Simply if you make the claim “life after death”
    You must prove it!!!
    And do not say I have to disprove it, since we are not the one claiming life after death , I say this:
    We don’t know what happens after we die because “No one came back to tell us”
    Logically and scientifically it’s more than impossible.

  27. Ali Adat May 10, 2019 at 4:05 am

    Away from philosophy and religion, this video has pointed out a very important point that many people are ignoring. No actions are taken in order to solve problems regarding to our beloved planet earth. Thanks for posting this video 🙂

  28. The Game Guy May 13, 2019 at 2:01 pm

    Send the bodies to space 🌌 when there's no space in the earth to bury the dead. 💀

  29. Glitched_ May 17, 2019 at 1:50 am

    I want to be thrown out, to decompose naturally

  30. Glitched_ May 17, 2019 at 1:52 am

    Wait, if we decompose then what happens to our consciousness?

  31. what’s up 124 May 18, 2019 at 6:22 pm

    life is short
    Don’t waste it on partying, alcohol, fornication, girls and drugs. Rather do charities, do good for your parents and children.

  42. DJ Hutcherson June 6, 2019 at 7:21 pm

    In 2013 I was in a head on collision with a pickup truck. In the ambulance on the way to the hospital, my heart stopped beating for 8 minutes until they revived me, so technically I had died. I have no memory of it whatsoever, so I can't say what it was like to be dead…

  43. Hassad Abbass June 9, 2019 at 8:16 pm

    energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.

  55. Prema Adhei Akhyar July 17, 2019 at 5:07 pm

    In ancient sankrit, it was stated that in every living creatures, the body is the most vulnerable and it will be distorted and destroyed no matter how much the evolution process is developed. But the invisible energy, which is unquantifiable (the only reason we can't distinguish it even with our developed scientific equipment)
    and can't be destroyed,
    "Nainam Chhindranti Sastrani…nainam dahati pabak..na kainam kledantyopa na śoṣayati mārutaḥ.."
    Our souls are so much powerful that it can take any other life form right after our death.
    Souls are actually from another dimension, came here to enjoy and learn about the planet..we mortal bodies are merely the mediums.
    Nothing else.
    I hope who ever reading this must be enlightened.
