Cutting the grass could save your life.
A new study has revealed that one in ten early deaths could be prevented if inactive people spent just 11 minutes a day mowing the lawn.
The team at the University of Cambridge says that 75 minutes of moderate exercise per week - just half of the recommended amount - could reduce the risk of early death, heart disease and cancer.
Boffins analysed 196 research articles about the health benefits of exercise involving over 30 million adults and the risk of early death and disease decreased the more somebody exercised.
The NHS recommends at least 2.5 hours of exercise per week but the study found that this figure gave only minimal benefit.
Soren Brage, one of the authors of the study published in the British Journal of Sports Medicine, said: "If you are someone who finds the idea of 2.5 hours of activity a week daunting, then our findings should be good news."
