Basically, if someone was thrown into a jungle, and I mean deep into a jungle so they can't get out easily, how rapidly would they die? Assume they have no training on how to survive in a jungle. The only things they know about jungles are what one could quickly skim off wikipedia, if that. Sorry if this is in the wrong forum, but I'm toying with this as a setting, and am wondering... well, how lethal is it? Can it kill you in days, if not less, from a combination of dangerous creatures, and perhaps, dehydration? Or am I overestimating how dangerous they are?
