Sorry if I came off the wrong way Christa, I wasn't having a swipe at emergency service workers. I have full respect for what you do. I didn't mean to imply that workers in those fields are weak in any way.
My comment was regarding how modern society creates so many morbidly obese people.
I know in some cases people have metabolic disorders and medical issues that can directly or indirectly cause them to gain weight, but in most cases it's simply the lifestyle choices people make. The garbage passed off as food certainly doesn't help, but in most cases it's a matter of choice.
