I watched the entire documentary about a year ago, its very interesting how he co-exists witht he bears without weapons. For those who have not seen it, he gets pretty close and stands out in the open with a good number of grizzly's and they do not attack.

I believe that the bear that attacked him was a rougue and outsider to the group. They said the he was starving because the other bears forced him out when they saw him right?
