Humanity only uses 2%

Human beings only use 2% 
of our body weight to think. 
It's 
enough. We 
can't expect more
from ourselves. If
the square-cube law
were repealed, perhaps
then we could have brains 
fully 100% of our prior body
weight. 

Would you be okay
weighing double 
what you weigh

now, though? Just 
to be able to use 100% 

or would you consider it 
vain?  

To have a brain as big 
as you are, finally? Get
the intellectual respect you 
deserve! It would be so huge 
outside the current bounds 
of your head, it's hard 

to imagine how you'd 
manage. Perhaps the double-you-up 
brain tissue could be spread throughout 
your body like fat cells, or in place of. 
As the transformation hits, you'd 
BALLOON UP, your mind racing 
with the entire collected thus-far 
knowledge state and fact-spate 
of humankind, which you'd just be 

sucking out of the air, basically. 
With your big-ass brain. 

Meanwhile though, sad myth 
it's not but an average fact. 
You, my dear, use only 2%

of your body to think. 
You know what would boost 
the percentage enormously? 

What if you cut off your limbs?
