With no explanation, label text_A→text_B with either "DON'T KNOW", "NO" or "YES".
text_A: Costs can include payment for medical personnel to be on call for death, vitrification, transportation in dry ice to a preservation facility, and payment into a trust fund intended to cover indefinite storage in liquid nitrogen and future revival costs. As of 2011, U.S. cryopreservation costs can range from $28,000 to $200,000, and are often financed via life insurance. KrioRus, which stores bodies communally in large dewars, charges $12,000 to $36,000 for the procedure. Some customers opt to have only their brain cryopreserved ("neuropreservation"), rather than their whole body.
text_B: Is it possible for customers to preserve their complete heads, and not just their brains or entire body?
DON'T KNOW.
