“Mush” is as scientific a term as “person” :-)
A-ha! Good point. What you're saying is that the notion of "personhood" cannot be defined with scientific precision in the first place.
Would've been a good thing for scientists to emphasize before they weighed in on the Schiavo matter, and before "science" was used by large #s of commentators to "prove" she was no longer a person, eh?
