Two hikers are walking through the woods when a huge brown bear suddenly appears in the clearing about 50 feet in front of them. The bear sees the hikers and begins to head towards them. The first guy drops his rucksack, digs out a pair of sneakers, and frantically begins to put them on. The second guy says, “What are you doing? Sneakers won’t help you run faster than that bear.” “I don’t need to run faster than the bear,” the first guy says. “I just need to run faster than you.”
