Parents always tell children eager to watch storms to stay away from windows while lightning is flashing. Technically, they're right – Jennings says that lightning can go through a window that's closed, and there's often metal on a window, which can electrocute you. However, while it's never a bad thing to be on the safe side, Jennings says there are only about 300 lightning mishaps a year in America. That puts chances of you being hurt by a storm at what is actually one in a million. "There are also costs to never getting to watch a dramatic lightning storm pass by, poetry-of-the-soul costs not easily measured by actuaries or the National Weather Service," Jennings writes.
