Ergonomics?

What is ergonomics?  Ergonomics are headaches, migraines, pain in wrist, forarms, elbows, neck or back, There are ways that you can  stop these from happening though. What are some bad habits of yours? Some of my bad habits are sitting incorrectly. Meaning my back is in the wrong spot and out of shape, bad posture in other words. Are our workstations ergonomically sound? I think that our workstations are ergonmically sound because they are far enough away and my elbows are in the correct place. Plus I do look down at the computer at a slight angle. How should people sit while working on the computer? I think that people should sit at computers with correct posture and good alinement. -Cheeto-
