28 Days Later - There was NO VIRUS

So going over all the issues surrounding 28 Days Later, I wanted to watch
the beginning of the film again...specifically the part in the beginning
when the monkey is watching the riots on the tv screen.  I was wondering if
the monitors were showing the riots and effects of Rage that was already out
in the public.

I was wondering this because the scientist said, "In order to understand
Rage, we have to study it".  So it seemed like it was already released, but
they were also studying it in a lab under controlled circumstances.

After watching it again, I realized that the scientist never uses the word
"virus".  Even when he says, "They're infected with rage", the group that
broke in doesn't think he was talking about a virus.

It's a bit of a play of our language (and others) that he could say "rage"
and we would interpret it as "Rage".

So what was happening was... the monkeys were being programmed alá
Clockwork Orange for rage by repeatedly watching instances of human rage.
This resulted in a condition of intense rage which was then contagious to
humans via blood or saliva because.

This is to say that humans have rage within them just waiting to burst out,
and Rage (uppercase R) is a biological evolution of an emotional
metamorphosis.   

This would mean that while blood or saliva can trigger the metamorphosis, it
is not virus based which means it can be triggered through prolonged
environmental factors...which is how the monkeys got it.

This would explain:

1) Why it only took 10-20 seconds to become Enraged.
2) Why the infected only went after the non-infected.
3) Why humans and monkeys were only infected.
4) How Rage traveled outside of England (if it did).

We also know that Jim, while not infected, became enraged by the
environmental factors.  Did you all notice that the imprisoned Rage victim
gave Jim a look like as if he recognized Jim as being one of them?

There's also the Simpsons scene with the rogue soldier.  That was also my
favorite Simpsons moment. I'm thinking the soldier, who was called a new age
philosopher by the others, had insight into what was going on beyond just
being the only one understanding they were being quarantined.  In other
words there was semi-rage going on and this soldier "being enlightened" was
less raged and therefore could think rationally about what was going on.  I
think what he was trying to say was that in America, there's no focus on
what's going on that would cause rage...there's just the Simpsons and no
reason not to watch it.
