Survival Rule of 3s

Humans can survive for: 3 minutes without air; 3 days without water; 3
weeks without food (but only just). Well, that's in real life. In
the disaster movies it's quite a different scenario. We saw "The Day
After Tomorrow" last night (were they really pumping freezing air into
the cinema?) and noted that the main characters (those who were still
alive at the end of the film!) had survived on candy bars and potato
chips. I guess that doesn't really count as being "without food" but
it certainly wouldn't have made their dentists happy! It's amazing how
people see different things in movies, isn't it? I noticed that while
the NY library characters were busy burning books to stay warm (that
isn't much of a spoiler!), there seemed to be a few chairs lying
around that could also have been used for fuel - unless of course the
wood was chemically treated and they might have been killed by the
release of toxic fumes. My partner noticed that at one stage a
policeman's vest had letters obscured and now read, simply, "ice".
Nice touch. Of course, "The Day After Tomorrow" IS a disaster movie
so doesn't count as "quality entertainment" but it's worth a look -
the special effects are amazing! - and it does carry a message, as
long as people choose to listen. Maybe some governments who have so
far resisted could warm to the idea of the Kyoto Accord?
