    A union of two sets is a set that contains all the elements of the two sets.

    A=\{ \mbox{ all men } \}
    B=\{ \mbox{ all women} \}
    Then,
    A\cup B=\{ \mbox{ all people (except TPH for he is not human) } \}

    The intersection of two sets is a set that contains all elements that are in both sets.

    A=\{ \mbox{ all people with hair } \}
    B= \{ \mbox{ all people with eyes} \}
    Then,
    A\cap B=\{ \mbox{all people that have hair and eyes} \}
