>>2143480I also don't believe this.
One time hiking with my dad (who is a respiratory therapist) we came across a dude hiking through whose skin was basically grey and he was wheezing and covered in sweat. My dad was like "that guy's about to go into cardiac arrest and I'm not deal with it" so we hiked up a side trail to check out a lake for 30mins or so.
Anyway, yep. Apparently that guy ended up getting carried down the mountain. Dunno if he died or anything
