Internal Advantages

GURPS Bio-Tech page 97 and GURPS Power-Ups 8: Limitations page 9
Note what would apply to something like Corrosion Attack and Leech to reflect digestion:
:"costs assume the internal advantage is usable anywhere within the body. If it can only reach certain areas, this is a -50% limitation"
This actually would reduce costs to 1/10 if it only applied to a stomach, for example.
The human brain probably should have this built in. High Pain Threshold is normally 10 points, and "brain that can't feel pain" would be a perk that most people would have.
