Can the Government Track You if You Have a GPS-enabled Phone?

So much for laying off the grid...

Phones such as the iPhone, that have built-in GPS usually have an anti theft feature that allows the phone to advise of its location. But the feature needs to be enabled and the phone must be switched on. This is also only designed to allow the owner of the phone to locate it but, in theory, the police could also access the feature. A lower-fidelity version of this is already used by the police to locate criminals and missing persons by detecting which cellular mast your phone obtains reception from. This will normally only pin-point you to within 100m but it doesn’t need a GPS receiver and it also does not need you to be actually making calls. As long as the pjone is on, it will work.

Lobsters don't have a central nervous system so technically can't feel the pain.

Why are lobsters cooked alive?

Lobsters and other shellfish have harmful bacteria naturally present in their flesh. Once the lobster is dead, these bacteria can rapidly multiply and release toxins that may not be destroyed by cooking. You therefore minimise the chance of food poisoning by cooking the lobster alive.

That’s great for us but what about the lobster? It has been argued that lobsters do not possess a true brain and so can’t feel pain. It is fair to say that they are not self-aware in the same way that we are, but they do react to tissue damage both physically and hormonally, so they are obviously capable of detecting pain on some level. In fact, the hormone that they release into the bloodstream, cortisol, is the same one that humans produce when hurt. But the most visible sign of distress is the twitching tail, which evolved as an escape reflex. Researchers at the University of Maine found that putting the lobster on ice for 15 minutes before dropping it into boiling water produced the shortest tail-twitching interval (20 seconds).
Contrary to the popular urban myth though, placing the lobster in cold water that is then slowly brought to the boil does not anaesthetise the animal and appears to extend its suffering.
