Then if you transplanted a set of components X from a person of age 30 into a person of age 60, then the person's resulting age should logically be somewhere between 30 and 60, skewed towards 60 if X is small (one drop of blood) and skewed towards 30 if X is large (everything except the brain).

No, you ignore the effect of the body fighting transplants because they have different DNA. The brain also learns to control different parts of the body when it's young and when you change those parts of the body in a way that makes them react differently to neural impulses the body get's less efficient.

body fighting transplants (hey, that's close to being a contronym, how awesome is that)

Just to complete the set, there's also the inverse: the transplant fighting the host ("graft-versus-host"). Imagine how confused you'd feel as a sentient leukocyte, grafted onto a different body.
