If you want to live longer, then all you need to do is take a break. Press pause on whatever programme you’re watching, get up and go into the kitchen and put the kettle on for a cup of tea. This little burst of movement can make a huge difference to your longevity, according to Cork-based GP and TV presenter, Phil Kieran.

This is because research shows if you sit down for extended periods in the evening, for example, for more than 45 minutes to an hour, it has negative impacts on your metabolism, says Kieran, who will be soon back on our screens presenting RTÉ’s health new show How Long Will You Live?
