how can anyone assign meaning to three numbers...
664, 665, 666, 667, 668....one number in a sequence of numbers. nothing more to it...
what i read was a load of superstitious crap, sorry for my blunt interpretation..the whole thing was probably made up by the japanese anyway...there the most superstitious people your likely to come across, for instance, i was working on a mazda rx7 and i never came across a 13millimetre bolt anywhere, and i stripped that car...
mazda beleive that the number 13 is unlucky, and if they made 13millimetre bolts it would make the cars dangerous and unlucky to drive...
what a load of crap, a 13 millimetre bolt has more mass and therefore more strength than a 12millimetre bolt...
too much superstition in the world, because no one understands something they come up with the most bizzare, out of this world and crazy ideas...walking under a ladder, breaking a mirror, all made up and all crap....
that is all
