I guess I'm what you would call, a convinced jerk. I hate being wrong,
last year, a college of mine told me something like this (I don't
remember the exact words): "I hate discussing with you, even when you're
wrong you appear to be right." It was a great complement, it was like in
Socrates' trial when the accusation said: "Socrates, the men that can
make a poor argument to look like a good one." (or something like that,
the idea is the same) Anyway (instead of admitting I'm wrong, I'm just
praising myself), yes, it can be interpreted that I claimed human cells
more difficult to cryosuspend than frog cells and microorganisms simply
because they are more complex. It was a mistake, I was wrong. It wasn't,
however, my intention to make it susceptible to this interpretation, my
idea was, like I mention in my last message, human beings are more
difficult to cryosuspend than frogs and one of the reasons is because of
complexity since humans are more complex, they'll have more types of
cells and the chances of errors occurring would increase and etc (I
already wrote about this, no need to bother you again).

I'm not satisfied with this definition either, I said that "complexity"
is hard to define, if you have a better idea I'm all hears.
I cannot think of any organism with many different types of cells and a
simple organization, how do you define simple organization? Number of
cells? Number of tissues?
Anyway, when analyzing species like we were (frog vs. human and
microorganisms vs. human), one can clearly see what is the most complex.

No, about 93% of Americans are religious (you're Canadian right?),
therefore asking for religious explanations is never a bad choice.
Extropians are not known for their religious minds but perhaps you are
religious (well, now it seems pretty obvious that you aren't). It was an
attempt to understand your ideas, I made other attempts, I asked other
questions. I didn't find anything spiritual in your sentence but that
doesn't prevent me from trying what is the most common hypothesis for
explaining any phenomenon, that is, religion. I missed in this attempt
and, like I said before, I'm sorry if I offended you.

My God, I play soccer 2/3 times a week. I wonder what that means? (just

neurons (naturally, of course)?"
Is the word naturally applied to soccer? Is the word naturally applied
to poles going through one's head? I don't think so. Some non-aging
animals like some sharks appear not to lose any brain cells (or lose so
few that it goes unnoticed). The lost of neurons is caused by aging or
exceptional events (like shooting yourself in the head, taking some kind
of drugs, playing soccer).

It was a joke! Don't you have any sense of humor?
Speaking seriously now, it is a proven fact that women have fewer brain
cells than men and that women have a smaller, lighter brain. More
important, it is commonly accepted that women are less aggressive which
gives them a disadvantage in most professional careers (not to mention
the fact that women have to give birth).
During World War 2, the British industries noticed, for the first time,
the fact that women are better workers, when it comes to organization
and concentration in small tasks during mass production, than men. In
Portugal, the percentage of women in universities is higher than the
percentage of women in the population. I think that the explanation lies
in the facts observed in WW2, that doesn't make women better
professionals than men, like you can witness from the winners of Nobel
prizes and the facts I mentioned above, it's actually the contrary. I
have an article in my site that mentions this, it's a simple "Essay on
Intelligence" (http://homepage.esoterica.pt/~jpnitya/science/iq.htm).

Although there is an indirect relation between intellectual development
and subversion in humans, that doesn't mean that a being of higher
intelligence is more difficult to subvert, besides, there are exceptions
to this relation. The only example of high intelligence that we know is
our species and therefore all divagations of how an entity of higher
intelligence than ours would behave are just that, divagations. If I
build an entity more intelligent than myself, I'll surely find a way to
control it, I can think of a million ways to do this depending on what
entity we are talking about (from physical controls like drugs to
psychological ones). You say that this entity is more intelligent than
me in every way, do you include irrational mental capacities like
determination and leadership? That might be going a bit too far, it all
depends on the purpose of creating more intelligent beings.
Anyway, this is pure speculations, our brain is still a huge mystery.
Have you read "Descartes' Error: Emotion, Reason and the Human Brain" by
the brilliant Portuguese neurologist Antonio Damasio? It's very
interesting.
I can't stop noticing that we are drifting a bit out of the original
subject,
