No Neck

No Neck is a version of Injury Tolerance.
Some might assume it's included in Diffuse but http://www.sjgames.com/pyramid/sample.html?id=5583 pays for them separately
B137 mentions having this removes veins/arteries in the neck, which can be compared to how No Blood removes veins/arteries EVERYWHERE.
This arguably could be perceived as No Neck having "No Blood (Neck Only -80%)" built in as a perk, which perhaps should mean having them together should be cheaper.
