    Take a look at this fan from the first half of the 20th century:

    Note that it has a guard which protects the blades in case the fan falls over. However, the guard does not protect a person from accidentally sticking his fingers into the fan. Why not? It’s not exactly complicated, it would have taken just a little more wire, and I’m sure people back then didn’t enjoy having their fingers struck by metal blades any more than we would now.

    People can be weird about safety…
