I may keep a candy bar nearby just to read this thread!  The Tractatus
Paleosophicus no less.  Heavy:)

Seriously, as to Amadeus's joke (there is truth in jest here, right?), how
much energy is used by the brain in 'heavy thinking?'  I have come away
from some types of problem solving nearly exhausted.  My question, Is this
feeling of spending a lot of energy primarily from thinking, or are there
other significant factors?   Wenn man über dieses sprechen kann, bitte
seien Sie nicht leise.

Vielen Dank
