So, this is an article about how high-altitude mountain climbers have high instances of gastroenteritis because other climbers are shitting in the woods instead of disposing of it properly, and when it’s freezing cold, washing your hands with soap apparently isn’t a high priority.

“Furthermore, fewer than half said they always washed their hands after defecating, with 16% admitting using rocks and snow instead of toilet paper. A shameful 11% confessed to pooping directly into the snow.”
