As I read it, he was following a trail from a RESORT. There was a trail, a path. When he got turned around, where did he go, down another path? Down a game trail? Into the jungle? If it was another path, well, okay, but.... Game trails are usually about 6" wide & should have been obvious that this wasn't right. If he went into the raw jungle, his brain was in neutral.
Hey, I've gotten lost! I stopped and sat down and thought. Twice, while I was pondering, I heard people, found them by yelling, and they set me straight. The other time, I got out just by thinking. OTOH, I usually keep looking behind me to see what the terrain looks like from there, but this may be a total waste of time in the jungle.
What was this guy doing, anyway? What was he looking at? Didn't he notice ANYTHING about his surroundings that would have tipped him off really soon that he had gone wrong? It took him HALF A DAY to realize he'd made a mistake?
And this guy is a WILDLIFE biologist. Am I completely off track here, or does he not routinely hang around out in the brush? AND without even a few basic necessities???
He was lucky his cell phone even worked there. And if it hadn't? Another moldy body lying in the jungle with all the blood sucked out of it by mosquitoes.
"The worst part was when a helicopter flew over on the last day and didn't see me. I screamed and shouted..." (Tittering here!) He's watched too many movies! There isn't a chopper pilot in the entire world that can hear someone on the ground shouting! Get real! Take off your shirt and wave it! Start shaking a tree branch, anything but wasting your energy shouting at a helicopter.
He may be smart. He may be educated. But he hasn't got the sense of dryer lint. And he's DAMNED LUCKY!
