*thinks about it* Seems to me like six of one, half-dozen of another,
but then again, centrifugal force is a nonexistent force conjured up to
describe motion in a particular frame of reference, too...from an
outside point of view, the math is easier/makes more sense when you
reduce everything to a single set of common elements with no overlap.
But having a word for 'suck' is handy for us lay-people--lets us
describe life in a shorter phrase than "region of low density of
pleasantness at self causes misfortune to be pushed onto me", as "life
sucks".
