A man was riding a mule along a steep mountain trail. Suddenly, a cougar darted in front of him. The mule spooked, pitched him from the saddle, and ran further down the trail, taking the man's gun, gps beacon, and supplies with it. The man tried to run, but found that his ankle was broken. He attempted to back away, instead, but his ankle collapsed on some loose stones and he fell backwards toward the precipice, catching himself at the last moment on some old tree roots. As he hung there, with the cougar pawing at the gravel above him and the roots beginning to come free of the rocky soil, he saw a bright cluster of wild berries just within reach. In despair, the man leaned out, grabbed a handful and began chewing on them -- to his surprise, they were wonderfully sweet! Savoring their taste, the man decided that he had, by all rights, lived a good life, and he braced himself for the worst.
Suddenly, the cougar pounced! The man jerked back, and to his amazement, the cougar sailed past him, lost its footing on the slope it had aimed for, and plummeted to the canyon floor far beneath. A cascade of tiny stones followed the big cat, and larger stones followed those. The man looked around and realized that a larger set of tree roots had been revealed beneath the shifting stone. He wiped his free hand, reached out, and got a secure grip. Within a minute, he was back on the trail. As he was catching his breath, he saw his slightly skittish mule trotting back down...
