Is where a person's life or safety is endangered: where there is concern for an elderly person or some other person, or where a shooting, fire, or explosion has occurred?

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.
