At the momemt strange things are going on with DAN. This story is that far from reality! Also the DAN study comes with huge deficits and maybe wrong conclusions...it seems DAN left the path of true science and being a source for reliable information 🙁. By the way: this blog is nice to follow along for technical divers. https://www.dekoblog.ch/post/can-a-mouthpiece-retaining-strap-save-an-unconscious-diver @scubadivers #diving #scuba #scubadiving #technicaldiving
