EB questions

Basically, if the biological system just isn't getting the info that tells it it's dead it'll try to keep going as if nothing had happened until complete shutdown, of course barring sufficient damage to something critically important (brain and the rest of the CNS mainly - the processing unit and/or datapaths go, the system goes). AFAIK people sometimes pull off that sort of scary stuff just by the natural hormones of their brain, but obviously to achieve that sort of effect even remotely reliably it's better to turn to, shall we say, uncommon measures.

The first one's free...

Kinda the same thing that necessitated the crossbars on boar-spears and -swords, save in humans. Armed, skilled and crazy humans. Bet you there were some odd bits about the Celtic views on afterlife that played an important part in the emergence of the Gaesatae tradition.
