If you spend most of your days sitting at school, work, at a computer or stretched out on a couch at home, you may be taking up to two years off your life. It is ＿＿（41）＿＿ that a sedentary lifestyle increases the risk of heart disease, Type 2 Diabetes, cancer and obesity, and can result in early death. Many people think they can make up for sitting around by walking, playing sports or going to the gym. ＿＿（42）＿＿ , this might not be so. A new study just published in the journal "Annals of Internal Medicine" suggests the effect on our longevity from sitting for long periods of time cannot be changed through exercise. Even 60 minutes of daily exercise may not be enough. The study is from Dr. David Alter and his colleagues at Toronto University. Dr. Alter and his team analyzed 47 studies that ＿＿（43）＿＿ different groups of people, who kept notes on how long they sat down each day and how much they exercised. They found that the most sedentary groups had a 24% increased chance of dying than the ＿＿（44）＿＿ sedentary ones. This remained the case even though those who sat a lot also did 60 minutes of daily exercise. Dr. Alter writes： " ＿＿（45）＿＿ your sit-down time by 2-3 hours each day by standing up at your desk, taking frequent breaks to stretch and walk, or watching TV on your feet may be better than an expensive, crowded, smelly gym and be just what the doctor ordered."
