doesn’t the strength of the branch matter infinitely more than how much I believe/hope/think the branch will support me?
Jack, I don’t understand this concept.

Hi, Michael. That’s not exactly what’s being drawn out here. The strength of the branch is what it is. So grabbing it is going to save you whether you call it a branch, or a vine, or a stick, or a root. You don’t even have to be able to see it or call it anything, so long as you wrap your hands around it in the dark and hold on.
