What a world: The kilogram is shrinking. That is, either it's shrinking or the other kilos it is compared to are growing; there's no way to be certain.
To add to the fun, there's no consensus on what should replace the present physical standard. Most of the other basic units have some derivable definition, such that given a physics lab and a few tens of thousands of dollars, you could dope out your own Meter or Second (and feed a starving grad student). Not so with the unit of mass.
You realize that if each kilogram is lighter, it looks like I'm getting heavier, don't you? So unfair!
