No Vitals

No Vitals is a form of Injury Tolerance.
GURPS Bio-Tech 172 introduces Testicle Tuck as:
:Injury Tolerance (No Vitals; Partial, Vitals, Groin only, -60%) [2].
So it might be thought of as No Groin.
The Heart is presumably one of the vitals too, since No Vitals gives immunity to Heart Attack under Mortal Conditions.
It's not clear if it's possible to just get No Heart (but still have other vitals like kidney or groin) though it would make sense for this to provide at least a token limitation, even if it were less than -20% and not enough to save a point on it's own.
