Staying inactive can also be a really bad habit because of the negative effects it has on your body. Studies have shown that people who are inactive, including those who sit at a desk all day with minimal movement, are at higher risk of all sorts of diseases ranging from heart disease to cancer. If you’re in a position where you spend a lot of time sitting at your job, try getting up every hour or so and walk around to get a good stretch and some blood flowing through your body. Research also suggests people who work out 150 minutes a week live on average ten years longer than people who don’t.
