You know how "when lightning strikes" is a metaphor for the highly unlikely? It turns out that the odds aren't that long. According to National Geographic:
The odds of becoming a lightning victim in the U.S. in any one year is 1 in 700,000. The odds of being struck in your lifetime is 1 in 3,000.
Lightning strikes aren't a lottery, of course. During thunderstorms you can influence the odds by (for example) standing next to -- or better, not -- tall conductive objects.
