Trope-a-Day: Healing Factor

Healing Factor: Another thing on the list of Stuff That Gets Engineered Into Everybody, although it’s not exactly the bizarre cinematic version that lets you come back from one cell, and beheading, exploding, or other long-term loss of essential functions will still kill you.  It does, however, include an extensive cellular-level emergency oxygen supply, a smart vascular net to prevent bleeding out and loss of blood pressure, improved blood clotting, pain gating and suppression, faster healing without scarring, anti-embolism filters, superior anti-infection systems and toxin resistance, and the ability to regrow severed limbs, and to regrow nerves up to and including spinal cord injuries.

It also does make you hungry as all hell when it kicks in, yes.
