Good summary. Especially the healthy people being hard to measure. Never heard anyone put it that way before. Now that I think of it, it's usually easier to tie data points to specific illnesses than to a lack of them. I have a feeling I'll be wondering about this in the future.

Quick guess is that healthy relies on emergent behavior of locally interacting cells. Lots and lots and lots of complex behavior with few observable inputs and outputs into the body. The inputs might not have a direct correlation to healthiness. We'd have to have a model of all those processes before we'd see evidence of healthiness in the data points.
