Most of the 'vaguely dissatisfied' types are N of the equator.
I remember reading some research which indicated that peoples moods were positively affected around the Vernal Equinox (Spring), and negatively affected around the autumnal Equinox. (ie now...well for you guys up ^ anyway).
Me...I'm fine with my hobby, and hanging out for the next 'big thing'.
Just sayin'.
