Could I just add here, along the lines of irrational thought, that I have just eaten too much chocolate?
"... preliminary research at West Virginia's Wheeling Jesuit University suggests chocolate may boost your memory, attention span, reaction time, and problem-solving skills by increasing blood flow to the brain..."
http://faculty.washington.edu/chudler/choco.html"Adam Drewnowski at the University of Michigan [...] found that eating chocolate causes the brain to produce natural opiates, which dull pain and increase a feeling of well-being."
Not that I'm trying to justify my own chocolate addiction or anything...
