Jonathan Davis and his wife, Alexis, are 55 years old and have one daughter, Joanne. Jonathan and Alexis live in the same neighborhood as Joanne, who visits her parents frequently.

Jonathan has smoked one pack of cigarettes every day for the past 30 years and is 20 pounds overweight. He works in a local plastics manufacturing plant and has a physically demanding job. Alexis enjoys working in her garden and cooking a variety of vegetable-rich meals. Joanne exercises regularly but does have asthma, for which she uses an inhaler when needed.

The community where Jonathan, Alexis, and Joanne live has extensive walking and biking paths. Joanne makes full use of the paths and bikes on them at least once every week. The community has recently instituted a wellness clinic about three blocks away from Jonathan and Alexis’ house.

Although the plastics plant pollutes the river, the company plans to install water and air pollution control measures in about 3 years. The plant is currently implementing purification measures for the river.
