Amazon Prime has a documentary type movie on right now called Trapper Jake. Free for being a member. Like the description says, if you like Happy People, you'll like this. It follows around an old timer and shows a lot of trapping type stuff, including dispatching the caught animal. I don't recall them saying how old he was at the time they filmed him and it doesn't have a lot of sustenance living type of content, but it's an enjoyable story. Probably more so if you're a trapper.
