I get plenty of exercise - I walk to work. A study suggests that in many poorer areas of the UK, more than a third of adults get less than 30 minutes of exercise per week.
The study links inactivity to increased premature deaths in those areas. I'm not sure it's that simple. It didn't account for lots of other factors, such as the quality of healthcare or local demographics. It was also carried out by the leisure industry. Should people exercise more? I think so. Should studies like this be more rigorous? Yes!
