Study finds technological improvements contribute to less exercise

A new study says people have engineered their way to being less healthy.

Many technological improvements since the 1960s have reduced the amount of physical activity. Because of that, people have had to add more exercise to their daily lives.

In fact, the study found women alone averaged almost 26 hours of activity a week in 1965 outside of exercising.

That number is now down to just over 13 hours.
