Does fainting have any evolutionary advantage?

Or is it a biological flaw? What benefit does it provide if any if it isn't simply a flaw and has some actual reason behind it?

Update:

Don't know if I should put this here or in medicine

    In cases of extreme danger it can put you on the floor like you're a dead body, not something to be attacked (it works for bears), it doesn't allow you to scream like wounded prey, and it doesn't have you running, making yourself a target for a predator that chases things that run. It also allows the people still standing to be viewed as better prey to kill.

    In humans? none.

    There are animals that faint/fake being dead to deter predators. There are also goats that have a mutation who faint. It's not advantageous.

    There is no evolutionary advantage to having brown hair over blonde, being right-handed over being left-handed, or having blue eyes over hazel. These are just characteristics that are part of the genome and are evolutionarily neutral. Fainting... Or any other similar reaction would, for most people through most of human history be neither an advantage or a disadvantage.
