They are even insanely *shallow* projections if you consider all the [[Facets of Fitness]] and [[Health is Vague|health]]. ## The web & graphs Interestingly (to me, at least) - the [[Semantic Web]] and [[Graph]]s can get you a lot closer to "the whole" of a thing than traditional data approaches. **** # More ## Source - self
