I wouldnt say that. True, there is some shyt, you just cant come back from but:
Because trauma victims often die of blood loss, rather than the injury itself, stopping the bleeding is the top priority.
Before help arrives, a bystander on the scene of a shooting or other trauma like a car crash or construction accident may be able to save someone’s life by applying direct pressure to a wound.
Theres a reasons Police and Soldiers are thought basic 1st Aid.
If I remember right, simply covering the wound and applying pressure speeds up blood clotting which can save lives.
