This time some began to have bowel movements in order to lose weight. If you lose weight, you move faster. It comes from fear. I have seen this before in our hunting of large animals, when they turn on us and we have to escape quickly. Some in our group begin to drop the items that we need to eat and drink in order to survive.
Nothing matters now but survival.
Then something happens. One in our groups stops running. Because of the dust and confusion I can not see who it is, but it appears to be an older woman. Perhaps she is tired and can no longer run. It matters not.
