If you find yourself weak and near death out in the wilderness but in a situation where you know there is hope for rescue and you must try to avoid being eaten by the wild animals there is one thing to remember about how wild animals exploit vulnerabilities.
The first scavengers or predators on the scene will evaluate your condition and attack the softer parts of your body. That includes your anus and genital area, your stomach/gut area, your eyes and neck. It is in your best interest to cover those areas as best as possible. Those animals will try to create injuries that are serious enough that you will not survive so they go for the soft parts.
Buzzards are known to start at the anus/genital area and move into the gut area. when they are cleaning a carcass. Same with larger prey animals. Use your resources and energy to protect the soft parts and you will improve your chances of survival. Duck and cover by assuming a fetal position can work if you can maneuver your backside into a sheltered position where it is less accessible. Cover your ass in other words. When fighting back you should remain facing the threat with your rear covered.
