This happens all the time at my gym - someone settles down on a piece of kit, takes out their phone and just sits there for ages, like they're in an armchair, looking at their screen. Or does a bit over exercising, but then goes into their phone. Half the people in the gym were at it today. I 'n just thankful that you can't text and swim. Seriously though, what's wrong with people that they can't do an activity without having to look at their phones every few minutes?
