"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.

At twenty below zero and fifty miles an hour the wind ravaged the mountain.
