A broadly philosophically oriented comment [made from the same mold as K.P.
Collins's unifying understanding - an understanding that is unfortunately
being obscured/discredited/sullied by certain naively neurotic ideational
contents of his own communications] that calls for being made in view of
this interesting thought-provoking observation, is:

Living creatures [elaborately energy-moderating, self-replicating, locally
entropy decreasing/resisting entities of a cellular and multi-cellular form)
can also be characterized as 'consisting of', or be seen to involve,
intricate functures (for functional structures] that selectively and
adaptively block/stall/postpone cellular and inter-cellular instances of the
universal tendency towards increased entropy.
