<br>1) Will the freezing process (I don't care about the unfreezing process) induce turbulence in the fluids of the brain?<br>2) Will the brain really remain frozen until the age of Nanotechnology?<br>3) Will anyone in the age of Nanotechnology think we're worth the hassle of reviving? <br>

</font></span></blockquote><div><br>I don't understand the distinction. Whichever method produces the least amount of damage preserves the most information, and the more information transmitted safely into the future the more options there would be for anyone who thinks we're worth the trouble of reviving. <br>
