Why should we study Psychology?

They say that Psychology is really interesting, you get to know people and/or animals, and their behavior, you get to know why people behave the way people behave and that helps people understand themselves and others better. That is a reason to study Psychology, so we can understand ourselves and others, so we can coexist in the same community or society, so that our social bonds become stronger. Another interesting thing about psychology is that we are to study the human brain, which is the human body's most interesting and fascinating part of the human body.
