(NEW YORK TIMES) — Too much time spent in a chair could shorten our lives, even if we exercise, according to a study that uses objective measures to find the links between lengthy sitting time and death among middle-aged and older adults.

More hopefully, the study also suggests that we might be able to take steps to reduce our risks by taking steps every half-hour or so.

Most of us almost certainly have heard by now that being seated and unmoving all day is unhealthy. Many past epidemiological studies have noted that the longer people sit on a daily basis, the likelier they are to develop various diseases, including obesity, diabetes and heart disease. They also are at heightened risk for premature death.
