It's taken about 200,000 years of human history to get to this point, but apparently people have FINALLY figured out that you shouldn't go outside during lightning storms.
According to the National Weather Service, lightning killed 16 Americans last year, which is the fewest since they started keeping records in 1940.
Over the past decade, the average has been about 27 people a year. The previous low was 23 deaths back in 2013.
