If the brain processes "happy" faster than "sad" and the deep fundamentals are time and space . . .hmmm

Brain Detects Happiness More Quickly Than Sadness:
"The results, published in the latest issue of the journal Laterality, show that the right hemisphere performs better in processing emotions. 'However, this advantage appears to be more evident when it comes to processing happy and surprised faces than sad or frightened ones', the researcher points out.

'Positive expressions, or expressions of approach, are perceived more quickly and more precisely than negative, or withdrawal, ones. So happiness and surprise are processed faster than sadness and fear', explains Aznar-Casanova."
