　　E

　　American office workers spend an average of 52 hours a week at their desks, according to a statistic survey. Some might argue that not all that time is spent working, but still all those hours in windowless offices with artificial light can have an influence.

　　A few green additions could have a large effect on worker happiness, according to the survey led by Tina Cade from Texas State University.

　　“We pretty much found out that if you had windows and plants or even if you just had plants in your office, you were more satisfied with your job, ”Cade told LiveScience.“We thought it was important for offices because a lot of times people are looking for ways to keep employees happy and do all these expensive things like building a gym. Maybe for less investment they could put in a few plants in important places.”

　　The team surveyed 450 office workers in Texas and the Midwest, asking questions about job satisfaction and the work environments. When asked about their overall life quality, 82 said they felt“content”or“very happpy”. Only 69 percent of those who work with plants but without windows, and 60 percent of those who have windows but no plants, said they felt this way.
