Well *obviously* if somebody is likely to hit you, you shouldn't even be
in the same building as them, never mind the same room...

That's not the point. Don't you think that walking up to someone and saying "You
are going to die" is a little bit threatening?
"You are going to die"
"Yes, but not before you, bampot" WHACK!

Have you *met* me? I'm about as threatening as a baby panda. :-P

Yes, more likely they'll just LOL. :P

More typically, people do "...oh, it's just HIM" and carry on as they were.
The Trilby helps.

You know approximately how many people lived in a certain age and how
old they got. From then on it is a simple mathematical sum.
Say that we have 1000 people in year x and 1010 in year x+1. Assume also
that the average age in year x is 50 (and ignore second order effects
and wars) then 20 people will have died of that 1000 hence 30 were born
that year. There is a lot of room for improvement, but something like
that is the basic idea.
There is a table on http://en.wikipedia.org/wiki/World_population. Why
don't you write a program to compute it in Haskell? (my 12 billion was
computed by someone else and I only checked that it was roughly in that
order of magnitude. Would be nice to have an estimate and knowing how it
was computed)
If you go back longer, you are less certain, but OTOH the number of
people is so much less than are living now that it does not make much
difference. Remember that homo sapiens has only lived for about
2500-3000 generations. The tail backwards is not so long.

Oh yes you can. It is called a census. They have even done that in
china, which is of course the major contributor. I am sure they also do
that in the UK IIRC they also ask you for your religion and recognize it
if enough people answer it. Resulting in klingon and jedi and some other
strange ones to be official religions now.

Is that the one where you put one gain of rice in a corner of a
chessboard and double it on the next square? until you have 2^63 at the
last one?

Most people know they are going to die (or at least assume so, see
above). This line is mostly used in films and books meaning something
like 'you are going to die very very soon and I don't mean that on a
cosmic timescale'.

Only in your own eyes. You are a big fit looking fella. I would think twice
about having a fight with you.

Yeah. My problem is how you arrive at this crucial first step.

How can you be sure it's accurate? Maybe it says that there are 20,000
people in city X, but actually only 50% of the population replied. (Or
something.)
Sure, you have birth certificates and death certificates, but again, how
do we know those cover *everybody*? (Surely it must be pretty
comprehensive, but totally? Hmm.)

Yeah, that one.
Apparently 2^63 grains of rice is more rice than has ever existed in all
of Earth's history, or something absurd like that...
(Damn, I *wish* there was a way of reliably finding out numbers like that!)

Ah. So you mean, by telling somebody something you're assumed to be
implying that it will happen in an unusual way? (E.g., "soon".)

Heh. That's amusing... I've been in 3 fights in my entire life. If you
can even call them that. And hell, I get breathless just walking up
stairs. :-P
Still, you can see why I generally just don't talk to *anybody*. It's a
reasonably good way to avoid being punched. Just for good measure, I try
not to look people in the eye either...

People know they are not counting everyone so they also estimate how
many they missed. I leave that one as an exercise to the reader.

Then it is nor Warp's but slightly older, assuming that Warp is as old
as he claims and not one of the secret millennium old persons.

In most cases, yes. In your case it may simple serve as a form of self
mutilation by proxy.
