That was the reason why I consider myself as an altitude sickness survivor, even though were not on the akiki or other difficult trail, still nothing was incomparable when I tried to overcome altitude sickness and hypothermia.  I had survive once and I will never do it again.  At least I had tried.  I had read the pre-climb report but I choose to be different this time, if some take photos on knife edge, well my adventure was of different one.  But sooner or later I want to try the knife edge also, even though i’m a bit scary on cliff edges.
