Did you know?

Did you know? The tin hat helmet was introduced in 1915. After that the amount of head injuries skyrocketed, the higher ups freaked out, and they started to abandon it, until someone pointed out that the graph skyrocketing was because soldiers were now SURVIVING previously fatal head injuries.

And this is why taking decisions purely on stats and graphs is a bad practice: you have the data, but it's useless if you don't actually know what that data MEANS.
