deathlessness?

Alcor Life Extension Foundation, located in Scottsdale, Arizona, is one of two human cryopreservation institutions in the U.S. The bodies or severed heads of 67 " patients" lie in cryogenic storage... liquid-nitrogen-filled steel containers. These containers store up to four "wholebody patients" and six severed heads at –320° Fahrenheit.
The 67 bodies—mostly just severed heads—lay waiting for the day when science can figure out a way to reanimate them.
I found this article on it. It proposes some intersting ideas.
Joseph Waynick, Alcor's president and chief executive, believes deathlessness to be a possibility. "When physicians first wanted to transplant a heart from one person to another, they were laughed at and told it was impossible," he said. "I have no doubt the technology [to revive life] will become available."
Many scientists scoff at the idea, contending that the practice is little more than a dream and that current "patients" will never be successfully revived.
"Even if, in our wildest dreams, this proved possible in the future, the end result would be the preservation of a dead body, not the suspended animation of a person," said Michael Taylor, a Charleston, South Carolina-based cryobiologist with Organ Recovery Systems, a company specializing in transplant medicine.
The prospect of cheating death raises a host of philosophical, moral, and religious questions. But let's consider only the scientific aspects.
"The preservation that we're able to do today is adequate to preserve the critical information that we believe is important to the human personality and human memory".
Alcor, which is one of only two cryonics firms in the United States, now uses vitrification to cryopreserve human brains. Skeptics, however, say there is no evidence that such large structures can be successfully vitrified.
About 80 percent of Alcor's "patients" have had only their heads cryopreserved. (The company's most famous patient, Baseball Hall of Fame slugger Ted Williams, has had his head and torso cryopreserved.) "The brain is what houses your identity. It has your memories, all your stored experiences," Waynick said. "Without the brain, you might as well clone an individual, because you have a completely new person."
Alcor continues to use glycerol-based freezing for patients who have their whole bodies preserved, since vitrification of an entire body is beyond current technical capabilities.

While vitrification circumvents some of the problems associated with freezing, it raises other issues. Scientists must impregnate tissues with high concentrations of cryoprotective chemicals that promote the vitreous state, but these are potentially toxic.
"Being able to manipulate matter at the cellular level will enable us to repair a lot of the damage that occurs to an individual during the cryopreservation process today"especially those patients that were cryopreserved in the earlier years, where there was a significant amount of ice damage during the freezing process."
In the future, breakthroughs in stem cell research and cellular regeneration may enable scientists to regenerate a new body from a person's existing DNA and attach it to the person's cryopreserved brain, scientists speculate. Even against all odds, cloning is now possible. So why isnt this possible too? So where are their souls in this process of "reanimation".
hmmmm...
