I think the difference with jensjourney is that she lost over 10 stone by working hard and the plastic surgery was to actually improve her quality of life as she had so much loose skin left behind. I don't think she got them for free either did she? I know that she got a hefty discount but she actually changed her life around for the better so I don't deprive her of that.
Grace goes on a new diet weekly, stops and starts in a matter of a week and then photoshops all her pics to make herself feel better. I feel there is no comparison between the two of them. Grace could do it too, she's just too lazy to do it.
