Excellent post Akichow!
Who knows you and your personality well enough to recognize a change in behavior that is cause for concern.
It seems that this is overlooked, at least with many of the people I hike with. If I am organizing a Whitney hike it is rare for me to allow anyone to come that I have not personally hiked with. Primarily due to not having first-hand knowledge of their abilities and secondly for the reason you listed above.
...my first attempt at Whitney in 2009...
Thanks for sharing this story -
Very interesting, sobering and thought provoking. A couple of the hikers on an upcoming Whitney trip aren't too worried about AMS because they've never had it before. I am going to share your story with them!
