It's not strange to me. They are probably in awful condition and may be psychologically affected. I cannot imagine spending that much time in a pitch dark cave, much of that time alone and not knowing if rescue would ever come, and then having to go through that extraction process at the end. They've got to be traumatized to some extent - I know I would be.
Very true. I heard the coach taught them to meditate to help them thru the days.
