Seriously, why are Americans STILL not on the metric system?!?
and don't give me the old "because it would be cost prohibitive to change everything". you don't HAVE to change ANYTHING, just from now on use metric.
we already have to use metric when we buy anything made anywhere else, and metric is based on the decimal system, which would work fine with our counting (and actually makes it easier to sum measurements).
i just don't understand how we could remain so ignorant...
