anti-freeze and aeroplanes

I've been listening to a lot of old music (and by old I mean 5 years past or so..) and I came across this song that was all too familiar.. I never really knew what the title meant so I googled it and here's what wikipedia said:

Antifreeze is a cryoprotectant used in internal combustion engines, and
for many other heat transfer applications, such as electronics cooling and
chillers for HVAC. Compounds are added to water to reduce the freezing point of
the mixture to below the lowest temperature that the system is likely to be
exposed to, and to inhibit corrosion in cooling systems which often contain a
range of electrochemically incompatible metals (aluminum, cast iron, copper,
lead solder, etc.).

I suppose it was Scott's take on numbing the pain, basically. But with the kind of genius he is, it could've meant something more profound. I'm babbling.. I really have nothing else to say except that I miss hearing them.
