Cryonics is the practice of preserving humans in extremely cold temperatures after death in hopes that future medical advances may allow them to be revived. The document discusses the history and process of cryonics, including the first person cryogenically frozen in 1967. Cryonic supporters believe that vitrification can preserve biological structures and nanotechnology may allow for molecular repair and regeneration of tissues. However, critics argue that cryonics companies are scamming customers by promising immortality that cannot be delivered with current science. Some experts predict the first cryonic revival may occur around 2040 if repair methods can be developed.

1. REACHING FOR TOMORROW

2. 
Practice of preserving human
bodies in extremely cold
temperatures

Cooling people immediately after
death to the point where
molecular physical decay
completely stops

Patient held in such a state is
said to be in 'cryonic suspension’

3. Cryonics is justified by three facts that
are not well known:

Life can be stopped and restarted if its
basic structure is preserved.

Vitrification (not freezing) can preserve
biological structure very well.

Methods for repairing structure at the
molecular level can now be foreseen.

4. 
The first person to be cryogenically frozen was a 73-year-old psychologist,
Dr. James Bedford, wh-o was suspended in 1967.

In early 2004, Alcor had more than 650 members and 59 patients in
cryopreservation.

The most famous of them is baseball legend Ted Williams .

5. 
After a patient is declared biologically dead, Blood circulation is maintained.

6. 
patient is injected
with medicine to
minimize problems
with frozen tissue

blood is replaced with
cryoprotectants to
reduce ice formation

7. 
The patient is placed in
cold silicone oil, chilling
the body to -79°C

Moved to an Al pod,
cooled to -196 C in
liquid nitrogen.

Chemicals to activate the
cells of the body are
applied.

Placed in storage vessels
upside down.

8. 
Preservation of the brain of a
cryonics patient

Goal is to restore the patient to
health by regrowing a new body
around the brain using future tissue
regeneration technology.

Neuropreservation is less expensive
& the quality of brain preservation
is better than whole body
preservation.

9. 
Nanotechnology is a
technology which uses
atoms to create a desired
product

Nanorobots could be easily
injected into the
bloodstream, they would
then float through our
circulatory system to
locate & fix problem areas
of our body.

10. 
Nanobots will fully emerge after several
generations of partly-biological nanobot
forerunners have been constructed in
order to make them.

Adapted machine version of bacteria.

Silicon might make the ideal material
for its construction

a fine film of radioactive particles can
be adhered to the nanobot’s body as
energy source

11. 
Revival requires repairing damage from lack of oxygen, cryoprotectant
toxicity, thermal stress , freezing in tissues .

Survival depends on whether preserved brain information is sufficient to
permit restoration of all or part of the personal identity.

Pre-Repair Operations: The first step in low temperature repair is to clear
out the circulatory system.

Logistics System Installation

Fracture stabilisation : By the synthesis of artificial surfaces.

Tissue Chemistry Restoration : Denatured protiens are spontaneously
recovered

13. 
Mind transfer: Hypothetical
transfer of a human mind to an
artificial substrate.

Programming cells to grow a
new body: Programming cells
on the brain to regenerate a new
body around the repaired brain.

Nanotechnology

Critics say companies that perform cryonics are simply bilking people out
of their money with the promise of an immortality they cannot deliver.
Some cryobiologists predict that the first cryonic revival might occur
somewhere around the year 2040.
