"So what is luck, good or bad? Scientifically speaking, future chance events are by definition chance. They can turn out favorable or not. When a preponderance of chance events has occurred unfavorably, you've got bad luck. It's a fancy name for a lot of chance results that didn't go your way. But the gambler defines it differently. For him, luck refers to the future, and you've got bad luck when future chance events won't go your way. Scientific investigations into this have been inconclusive, but everyone knows that some people are lucky and others aren't. All we've got are hints and glimmers, the fumbling touch of a rudimentary talent. There's the evil eye legend and the Jonah, bad luck bringers. Superstition? Maybe; but ask the insurance companies about accident prones. What's in a name? Call a man unlucky and you're superstitious. Call him accident prone and that's sound business sense. I've said enough. "All the same, search the space-flight records, talk to the actuaries. When a ship is working perfectly and is operated by a hand-picked crew of highly trained men in perfect condition, how often is it wrecked by a series of silly errors happening one after another in defiance of probability? "I'll sign off with two thoughts, one depressing and one cheering. A single Chingsi wrecked our ship and our launch. What could a whole planetful of them do? "On the other hand, a talent that manipulates chance events is bound to be chancy. No matter how highly developed it can't be surefire. The proof is that I've survived to tell the tale." * * * * * At twenty below zero and fifty miles an hour the wind ravaged the mountain. Peering through his polarized vizor at the white waste and the snow-filled air howling over it, sliding and stumbling with every step on a slope that got gradually steeper and seemed to go on forever, Matt Hennessy began to inch his way up the north face of Mount Everest.
