Why is it that when I watch American police shows, they always get people to perform sobriety tests like 'walking the line.' In Australia we use a breathalyser, surely this is easier? | Typically, a cop in the US will do both for several reasons. 1) Breathalyzer results aren't always permissible in court 2) Some people become incapable of driving at less than the .08 BAC threshold.

Rare Earth Metals and why they are "critical components in the manufacture of various high-tech products, including DVDs, mobile phones, flatscreen TVs and hybrid batteries." | Rare Earths Metals are not actually rare, they just don't occur in great enough concentrations for people to go out and mine them in large amounts.
