A hypothetical situation
Let's suppose there is a situation where two persons are tied up with one hand on an edge of a steep cliff. If one lets go with a tightly crossed hand, the other would fall deep down into a valley. They are hanging on together in order to survive. But time is running out, they are getting tired of holding hands each other any more.
I have seen this kind of scenes too many times in the movie, pretending I would have done the same thing just as a hero did. However, that point has changed into a pragmatic perspective.
In a moment of the life and death situation like this, internal will could have influenced more than I can imagine. Which is I am beginning to realize an importance of mind stuffs. But at the same time, I am also fully aware that I can't beat the odds that easily.
This is only a hypothesis to stimulate imaginations.
