If you spend most of your days sitting at school, work, at a computer or stretched [up / out] on a couch at home, you may be [giving / taking] up to two years off your life. It is [commonly / common] knowledge that a sedentary lifestyle increases the [risk / risky] of heart disease, type 2 diabetes, cancer and obesity, and can result [on / in] premature death. Many people think they can compensate [to / for] sitting around by walking, playing sports or going [for / to] the gym. Unfortunately, this might not be [so / such] . A new study just published in the [journey / journal] 'Annals of Internal Medicine' suggests the effect on our longevity from sitting for long periods of time cannot be [revered / reversed] through exercise. Even 60 minutes of daily exercise may not be enough. The study is from Dr David Alter and his [colleagues / collages] at Toronto University. Dr Alter and his team analysed 47 studies that [tacked / tracked] different groups of people, who kept notes [on / by] how long they sat down each day and how [much / many] they exercised. They found that the most sedentary groups had a 24% increased [chancing / chance] of dying during the course of the study than the [least / lest] sedentary ones. This remained the [case / cause] even though those who sat a lot also did 60 minutes of [daily / dailies] exercise. Dr Alter writes: "Reducing your sit-down time by 2-3 hours each day by standing [up / out] 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 / vet] ordered."
