Grumpiness is Good for You...+ a ROF-LOL video ---

"An Australian psychology expert who has been studying emotions has found being grumpy makes us think more clearly..."--Go to this link before watching the video- -
After you check the link-this video will make sense in its juxtaposition...
If you are easily 'offended' - don't watch the video - it is ROF-LOL funny--though :-)
