All the chunky chimps in my workplace (forces) are that way due to: sedentary jobs, eating crap and not exercising. It’s infuriating for me as they are the ones who are signed off sick due to dodgy knees, bad backs etc (stress from the excess weight). I get a bee in my bonnet about such folk, as those who do take care of themselves get to pick up their extra duties. So from a personal point of view that’s why fatties do my nut in 🙂
