Vacuum-cleaner fluff would probably do it, although I have no intention
of finding out.

Really, I'm very surprised to hear that. I wonder what the different
formulae were/are.

Town gas was largely hydrogen (with a substantial level of carbon
monoxide, which is why it was poisonous) whereas natural gas is largely
methane.

Hmm. Methane may not be actually poisonous (unlike CO), but it will
still asphyxiate. OTOH, I think CO has some anaesthetic effect
concentrations, so presumably a potential suicide dies whilst
unconscious.

I assume that makes CO preferable if (a) you have the option, and (b)
you're trying to end it all. The scrappage scheme will cause problems in
that regard though - IIRC some well-tuned engine-cat combinations now
emit virtually zero CO (although plenty of CO2, which kills pretty
effectively).

Macabre. Thread change?

And who remembers the famous BBC Spaghetti Farm spoof-documentary?

Ah yes.That was Panorama with Mr Dimblebum Snr.

I remember seeing it 'live' as a kid. And the spaghetti hung on the trees
was so badly done it was obviously a spoof. Despite the film focus being
as soft as they dared.

Did you believe it at the time?

Correct.

Oxygen is transported around the body by haemoglobin in the blood stream.

Carbon monoxide binds more readily and more tightly to haemoglobin than
oxygen so that at sufficient levels, though very much lower than needed
for asphyxiation alone with other gases, the body is deprived of oxygen
and dies.

From http://www.ebi.ac.UK/interpro/potm/2005_10/Page2.htm

QUOTE

Carbon monoxide (CO) binds to haemoglobin with a higher affinity (200x
greater) than oxygen, and at the same binding site.

Consequently, carbon monoxide will bind haemoglobin preferentially over
oxygen when both are present in the lungs - even small amounts of carbon
monoxide can dramatically reduce the ability of haemoglobin to transport
oxygen.

Levels as low as 0.02% carbon monoxide can cause headaches and nausea,
while a concentration of 0.1% can lead to unconsciousness.

....

People who smoke heavily can block up to 20% of the oxygen binding sites
in haemoglobin with carbon monoxide

....

By contrast, carbon dioxide (CO2), which is produced as a waste product
after aerobic respiration, binds to haemoglobin at a different site,
therefore does not compete with oxygen for binding to haemoglobin.

No. Kids tend to be quite aware it's All Fools day.

We were somewhere around Barstow, on the edge of the desert, when the

For me sheer

one CD.

CD? Move with the times, Daddy-O.

Run of the mill audio is much better quality (wrt bass, treble and noise)
than was common in the past, at least electrically. A cheapy MP3 player
connected via the headphone socket to a hi-fi amp and speakers is almost as
good as CD.

Should get your hearing checked;!..

One great advantage of middle-aged hearing loss is the fortune I save on
not needing real HiFi

Oh dear. A flaktoid! I'm not one for getting into willy-waving contests

What's a flaktoid? Something to do with lossless compression?
