I "agreed" to nothing of the sort. What I said was correct, namely, that NO 
rabbit kidney has been vitrified and recovered viable, and no viable rabbit 
kidney (even without vitrification) has been recovered from a temperature as 
low as that of dry ice. The recovery from - 50 C was an important advance, 
but it was NOT vitrification. And I reminded readers--not to denigrate the 
research, but to inject a note of realism--that a human brain is much larger 
and much more complex than a rabbit kidney, which still has not been 
vitrified (and recovered) after many years of effort.

A little humor to lighten things up, no doubt.

No, some are not better than none, if a false impression is conveyed. The 
impression conveyed is that these results were from Alcor-processed brains, 
which is not the case.

I do agree with Platt on one thing--the recommendation that newcomers, or 
those in doubt, compare the web sites and publications very carefully.
