you didn't really specify - but issues with wilderness survival are these things, in this order, in kind of a massively decreasing scale of importance:
1. exposure to elements (weather, temp, heat loss to ground during sleep, inability to build proper shelter). usually leads to death within a few weeks, if not a few days in wrong season.
2. water. sanitation, portability, proper supply, filtration.
3. fat loss. most people can find some form of food, barring idiotic self-poisoning. most cannot find good sources of fat. lack of specific fat-soluble nutrients kills faster than lack of food in general. jerky boy wouldn't survive long.
4. hygeine. eventually, having all the other things, not knowing wilderness hygiene will catch up to you. not knowing how/where to relieve oneself, not knowing how to dirt/sand/water wash ones important parts, not knowing how to sanitize living quarters and do the best one can to not get sick (after the concerns from the first three).
all other things really aren't important.
