For $200,000, one of the world’s
largest cryonics companies will
preserve your body when you die so
you can be brought back to life with
future medical technologies.

Alcor is the world’s largest cryonics company, and according its CEO Max
More, they’re signing up customers
from all over the world who want
their bodies preserved when they
die.

The premise for cryopreservation is
pretty simple, says Rose Eveleth at the Atlantic. In the past when someone dropped dead on the
footpath, that was that. Nowadays
we do everything we can to revive
the person, such as performing CPR
or rushing them to the hospital for an
emergency surgical procedure. Cryopreservation can be thought of
as the natural progression of this
desire to keep someone alive using
whatever means possible. "Cryonics
is the same thing,” says Eveleth , "we just have to stop them from
getting worse and let a more
advanced technology in the future
fix that problem.”

While no one has actually tested if a
cryopreserved person can be
brought back to life many years after
they've passed - because the
technology to revive them does not
exist yet - that's not stopping people from signing up to have the
procedure done anyway. At $80,000
to preserve the brain and up to
$200,000 to preserve the entire
body, it’s an expensive risk to take,
but Alcor isn’t struggling for business, with almost 1,000 people
signed up so far.

According to More, staff at the US- based Alcor facility keep a careful eye
on the health of their clients, and if
death is predicted, they stand by
their hospital bed until it’s time. Once
their client has been officially
declared dead, the staff can begin the preservation process. First they move
the client’s body to an ice bed and
cover them in a loose, slushy layer of
ice. A device called a 'heart-lung
resuscitator’ is used to get the blood
pumping through the body again, and some 16 types of medication are
applied to the body to prevent the
cells from deteriorating. Then the
client is prepped for surgery.

The next step includes draining as
much blood and bodily fluids as
possible from the person, replacing
them with a solution that won’t form
ice crystals - essentially the same
kind of antifreeze solution used in organ preservation during
transplants. Then a surgeon opens
up the chest to get access to the
major blood vessels, attaching them
to a system that essentially flushes
out the remaining blood and swaps it with medical grade antifreeze. Since
the patient will be in a deep freeze,
much of the preparatory work
involves trying to ensure that ice
crystals don’t form inside the cells of
the body.

With veins full of antifreeze, the
client's deceased body is now cooled
down steadily - about 0.5 degrees
Celsius (33 degrees Fahrenheit)
every hour until it reaches a final
temperature of -195 degrees Celsius (-320 degrees Fahrenheit) in about
two weeks’ time. It will then be
stored permanently in a freezer,
upside-down, and next to three
others like it.

"The science of tissue regeneration is
steadily advancing. But nobody
really knows when they’ll be able to
wake these patients up, or if they’ll
be able to at all,” says Eveleth at the Atlantic. "When forced to take a guess at how long we’ll have to wait
for medicine to catch up to save
Alcor’s members, More put the
number between 50 and 100 years.
“But it’s really impossible to say. We
probably don’t even know what repair technology would be used.""

Truth is, when u r dead, u r dead. No science, medice or technology can bring u bk again. This kind of crap only sells in the West, i trust my fellow africans!
