In 2003, a solo traveler through southeast Asia learned a valuable lesson: always pack snacks. The traveler, who remains unnamed, met Paul, an American with an 'easygoing, natural warmth,' at a youth hostel in southern Thailand. When staff mentioned a beautiful waterfall 'not far' away, the two decided to hike there, expecting a leisurely hour-long stroll. They brought no food. A mistake, as it turned out, of epic proportions.

Four hours of dense foliage, vine-climbing, and youthful naivety later, they found the waterfall - a 'glistening pool' that made the ordeal seem almost worth it. They jumped in, laughed at their poor time estimation, and started back. That's when things went pear-shaped. Within minutes, the traveler began tripping, then became confused and unable to answer simple questions. In hindsight, starvation and dehydration were the culprits, but at the time, it was just terrifying.

Enter Paul, who did something unexpected: he hoisted the traveler onto his back and carried him through the forest. When Paul's strength gave out, he dug through the traveler's bag, found old sugar and salt sachets, and whipped up a makeshift rehydration elixir - a drink that would make any sports drink company proud. It gave the traveler enough strength to hobble on.

Hours later, near the hostel, the traveler slipped on a loose rock and twisted an ankle. Paul again picked him up, carried him closer, then ran for help, returning on a motorcycle to transport the traveler the rest of the way. Paul walked back alone. He left the next day, never to be seen again.

Did Paul save the traveler's life? The traveler says yes, and we're inclined to agree. Also, a PSA: if you're going to chase waterfalls in the Thai rainforest, bring water, food, and perhaps a Sherpa.
