This was the headline in the paper recently.
The study looked at 300,000 men and women aged 25 to 70 over a 12 year period to try and find out whether physical exercise made a difference to death rates.
They asked the participants whether they took part in active, moderately active, moderately inactive exercise or whether they were totally inactive.
If the people were moderately active then there was a 16-30% reduction in the risk of early death compared to those that were inactive.
There were flaws in the research such as they only took into account the amount of exercise they did at the start of the study. As you know things can change.
Nevertheless there is more and more evidence suggesting that exercise is one of the most important things for good health. Making time for exercise-even walking every day will give great benefit.
