from watching that doco kinda ( Tim Treadwell ) got the feeling he knew that bear was under nourished and dangerous, think he even says something along those lines, and feared this bear, it seemed to be time to go, but he didn’t or couldn’t in time. I think his mental health could have been a factor but I would not be fast to dispel his confidence and self belief build up over the years of doing this, It’s like walk down this street every day it fills safe now some dodgy guy’s start hanging there, and giving people sh@t I think most people would still chance it, still up in the middle of no where by yourself or one other is not the usual human group mentalitly, but people do that too. I certainly would not take my chance with the bear, stuff odds the only real odds are 50/50
