Probably because her diet/nutrition is so poor. I don’t think she has a thyroid problem, her eyes have always been like that. She is obese simply because she overeats. Now, whether she has binge eating disorder, or just greedy, but the fact is, it’s not ‘glandular’ it’s because she eats complete and utter junk and large portions of it!! Charlie is the same, it’s not his thyroid either, it’s sheer, utter boredom I think…they have nothing else in their lives except planning the next meal, KFC, McDonalds, pukka pies and mash, roast dinners etc. I honestly believe he’s depressed, his life is being bossed around by Jane, working, visiting HER family, and watching his wages haemorrhaging out the door on this ridiculous ‘buisness’ of hers (and supposedly his!) he’s a 31 year old man with a dead end life, a fat, bossy wife and he’s staring into the 50 odd years of this…
