What is public health?

What is public health? My non-public health family and friends were always asking me that when I was in school, and it’s not an easy question to answer. Public health includes the environment (like air and water quality), health care, disease prevention, epidemiology (disease detectives, like in the movie Contagion), biostatistics (the numbers and research that shows us what health problems exist and how well our prevention programs work), health education (like your high school health teacher) and the psychological side of health (that tells us why people make unhealthy choices).
