'In this new millennium' 'Now that we're in a new millennium' <----typically followed by a slurry of inane idiocies (usually spouted by some brain dead dumb as a bucket of rocks inbred politician).
So...you flipped a page on your calendar & changed the date on your mobile. You bought a new agenda. BIG FAT HAIRY DEAL!
Why do I need stop what I'm doing to become more aware of ________( <------ add cause celebre here ) because 'its a new millennium'. You mean that in 1999 up until 23:59 pm some horrible disease, poverty, child predators, wasn't important & wasn't affecting anyone & was less relevant? Had I known that, I simply would've gone into DENIAL & kept my old calendar! For some odd reason, many NT type's ears prick up whenever someone with a microphone (a camera & a soap box) prefaces a statement with some clap-trap about 'the new millennium'. GET OVER IT: it's 2012 already & I can't think of any major change that has swept the planet due to masses of bedraggled humans shelling out a few bucks for a new calendar.
Any problem that really needs addressing on a global scale needed addressing before the end of the old millennium & will probably require addressing for a looong time to come.
