I don't know that the obese woman I saw yesterday had a serious disease or not, but I did overhear her in the physio suite where I was, saying she had diabetes and had had two toes removed making exercise more difficult. I DO know that not every single person who is seriously obese has serious health issues causing that obesity though.
I didn't point, stare, make fun of her or hurt her feelings, I smiled at her when we were both waiting for physio and mentioned how hot it was as I drank two cups of,water rather messily. Smokers should be given the red carpet treatment actually, given the amount of tax they pay if you're going to be that pedantic, they pay for their own healthcare a good few times over and also don't cost as much- they don't require industrial sized beds, theatre tables, ambulances, or get £8000 stomach stapling surgeries then complain to the media because their skin has stretched so much they now need skin removal surgery.
I think we lost a lot of ground when schools started considering cutting up a baguette, putting cheese and tomato sauce on it, home economics, and therefore cooking. Portion control is going the same way as the USA ie. ridiculous- my husband was there recently and ordered a chicken and pasta dish at a restaurant. He was given FOUR chicken breasts. FOUR. That wasn't a request, just their normal serving. That should serve a family, that kind of portion.
And I a, sorry but I don't believe for one moment someone at thirty stone is happy with their size- carrying an extra two stone is uncomfortable enough.
