Subject: "That's Incredible" program on "Eternal Life"-- also Parabios...

The program was reasonably accurate and pro-science.
 
On Cryonics they showed Alcor and explained things reasonably well. John  
Rennie, Editor in Chief of Scientific American, said it was a last-ditch  

insurance policy, and Aubrey DeGrey says they can't revive you yet, but he pays
 a little to a life insurance company each month so if he deanimates 

suddenly  he'll be covered for cryo. Someone else calls it a sci-fi pipe dream,
but the  narrator says that's what they called heart transplants too. Then it 
launches  into transplants and organ growth.
 
It was very encouraging that Scientific American was positive. Just a  

couple of years ago their Skeptic, Micheal Shermer, said you could freeze tissue
 but upon thawing it would be "hamburger". (Thus apparently denying the 
successes  of cryobiology, which nobody else ever doubted.) 
 
I've previously discussed parabiosis here, connecting the circulatory  

systems of two rats, young and old, as was done in the 60's. (The older rat then
 lived longer.)  The program makes no mention of that, but does show Dr.  
Thomas Rando of Stanford, who did it with two mice in 2007, and found damage  
repaired faster in the old mouse (cuts healed faster etc.) It's interesting 
 someone is still working on it. They hypothesize there is some single 

"youth"  ingredient.  That was hypothesized long ago, that some small molecule
mediated "age" and if we could find it and synthesize it we could make a  
fountain-of-youth drug.
