Once I made a comment to Ariana about how I was not that fast.
"The thing is you're not that slow," she replies. "It just has to be worth it."
She then proceeded to give me the run down on a theory she had been working on; energy efficient Carbieners.
The Carbieners aren't lazy, they are just energy efficient.
If they need to move quickly, they will move quickly, but only when necessary.
They will be on time for something if it is important. If things will go on just as normal without them, they will show up "pretty close" to on time.
They exercise, but only to the point to keep them from getting fat.
They could go visit their friends more (and they probably should). Usually they opt for making their house more enticing though so that they can stay there and have people come visit them.
Carbieners plan to have activities on their beds. This optimizes comfort and is incredibly convenient if anyone gets tired, as they do not have to relocate to sleep.
Though some in the world would like to think less of us for living this way, the truth is we are highly evolved organisms. The Carbiener children are simply preparing themselves for the end of the world. Everyone else will be running around wasting away to nothing while we continue on with life pretty much as usual. After years of perfecting our beings to function at the optimal efficiency, we will survive.
Who knows, maybe they'll have to donate our bodies to science. Make studies of us and teach economics classes about cost/benefit ratios and stuff.
