Er, seven adjustable wrenches? What for?

Unless of course, it includes both metric and imperial...

I don't get the privacy issue people have with Oyster cards.

The only useful information they could mine from your usage habits is roughly where you live and where you work. Guess what? Government agencies already have much more precise information about that than they could get from an Oyster.

#27 Hmmm, well I was an armourer in the Airforce, not an avionics geek, but i'm pretty confident that the radar and all the other receivers on the aircraft are designed with electronic warfare in mind. It's a huge part of air warfare.

Ok, lets assume for a second that these chips do contain some kind of "kill switch". How exactly is the enemy supposed to execute the code required to activate this switch? Or are we assuming that the manufacturers of the chip, all it's next highest assemblies, the systems integrators, and any subsequent mods teams are all in on this? It sounds pretty unlikely.

I've actually had the pleasure of being singled out for this gag at the show. No, I did not have a camera forceably inserted into my person. It's a camera trick, unsurprisingly.

And if your target is driving a diesel? Diesel cars are pretty ubiquitous in many parts of the world.

While I agree with you the the word addiction is often misused, I think that "problems with your life or outlook" as you put it, are often the root cause of substance addiction, too.
And as for changes in brain chemistry caused by substances, well, the brain can experience changes in chemistry without introducing chemicals, too. We call these changes in brain chemistry moods and emotions.
So I think the line between what can be addictive (gambling? cocaine? the internet?) and what can't is often pretty fuzzy.
Bottom line is we don't know much about what causes addiction, and even less about how to treat it.

Seriously, that "cleat" is an inferno waiting to happen. You might as well dip it in thermite and flick cigarettes at it.
