Actual Old Man Logan

Wolverine will be a badass until the day he dies, and he'll probably spend his golden years slashing and slaying his foes like he did when he was a pup, but the Old Man Logan storyline tells a different story.

And if that wasn't confusing enough the new Marvel movie Logan tells yet another story about the mighty mutant's later years, so which story is to be believed?

This video by The Warp Zone seems like the most realistic interpretation to me!
