Jen, I am a confirmed phrase poacher: our welder was being an arse today, so I said "get in the bag, bogan". It felt like an appropriate insult at the time. And if I ever visit Perth, you have to take me to places where I can get really silly masks and other inappropriate gifts!
My new phrase lately is "who stole the jam out of your doughnut?" I've now seen most of Snatch (where I stole that from), but the DVD was scratched, so... I don't know the ending! There is no closure! I have to see the ending now, because I have no idea what happens (don't you dare tell me) and apparently it's great.
Work's busy. This is my 5 minute lunchbreak. Daylight come and me wanna go home!
Zoh, you should just show that town who's boss... by leaving. Before it steals your soul. Before all the vitality is drained and your body is forced to walk the earth like a mindless drone. Which, I've concluded, is the problem with the majority of the world's population: they didn't get out in time.

Elise, if you only get a single breath (of pure nitrogen), then a lot of the time I think you will restart breathing because of the continuing metabolism. But if you're in that atmosphere for a little while (only a couple of breaths), then there's not enough carbon dioxide being produced to restart the reflex. I'm not sure if you can force yourself to continue breathing if you're in a nitrogen atmosphere, but it's odourless and colourless and all that, so you'd almost certainly not notice.
Oh god I'm a nerd.
And I completely agree about the people who let you make all the effort, and you're never quite sure what's going on with them. I tend to avoid them these days, and only go with their invitations if I've got nothing else doing. I generally give people a chance to start with, but if they mess me around, then I become very ambivalent.

Elise, the problem from my point of view is that the breathing reflex won't restart by itself after removal from a nitrogen atmosphere. There is still (generally) insufficient carbon dioxide present to restart the reflex, and so someone can die from a single deep breath of pure nitrogen. Actual death will not occur for a few minutes, but the person may collapse, unconcious, without feeling anything. Bystanders who come to their assistance may also succumb.
It'd make far more sense to have a low oxygen sensor than a high carbon dioxide sensor, as oxygen content is the more critical variable.

People need to go to greater effort to entertain me while I'm at work. So, as a result of this deficit, I've been wandering the spider intarweb.
And I've found out how breathing a pure nitrogen atmosphere causes asphyxiation. Hey, it's even work relevant (kinda). But in essence it's because the breathing reflex is based on carbon dioxide buildup, and not lack of oxygen. So, if you breathe in nitrogen, you keep breathing out carbon dioxide, so the breathing reflex doesn't work...
From an engineering point of view, it's a very poorly designed control system.
