PARIS (AFP) - People who exercise just a little bit each day may boost their lifespan while TV addicts could be taking years off their life, two studies published on Tuesday suggest. Chi-Pang Wen of Taiwans National Health Research Institutes and Jackson Pui Man Wai of the National Taiwan Sport University looked at more than 400,000 people who took part in a medical screening programme between 1996 and 2008. The volunteers were then followed for eight years on average. Compared with individuals who said they were physically inactive, people who were in a group of low-volume exercise had a 14-percent reduced risk of premature death from all causes, and a 10-percent reduced risk of death from cancer.
