I have three hearts, anon-san - a primary heart, a secondary backup heart, and an emergency oxygen recirc system for my braincase.  My combat software can continue fighting in excess of 30 minutes even in the event of total loss of consciousness, with a banshee switch in the event of brain death.  (And yes, I know that firmware modification is illegal.)

Besides, to even get the K-band neurotype designation, my brain is mostly human, I just have a few specialized submodules.  Partial-synthetic, not full, and so only subject to limited sanctions under the Human Dignity Act.

Don’t be so worried, Anon.  I’ll be fine.
