He fell ill in one of the deepest caves? That sounds ominous as fuck. What if he found some new bacteria or virus and getting him out is what starts the zombie apocalypse? 😱
Cave crawling is akin to mountaineering, in which it shares a lot of techniques. Except with a cave you don't exactly know what is after the odd opening. Ive known some of these people and they are unique. I saw reports that this cave had long vertices, so they had some effort getting him out of there on a stretcher.
