When you were a boy in your teenage days (and maybe later on), you might have had a kind of "quality measurement" for girls. A "10" would have been the absolute eye-catcher with all attributes that made your imagination work, whereas lesser gradings were reserved for the "normal" girls.
Now this system becomes scientific! Scientists from Oz developed a system that does the measurement for you. No need anymore to leave the computer and meet the girls: just scan through your image sources and watch the attractive ladies you're never going to meet! Gee.
