My brother's the GP. Mum never made him do the cooking, cleaning, ironing or any basic stuff you have to learn to do throughout life. And now mum wonders why everyone has to clean up after him. I've told her it's because she never made him do any of the cleaning etc and mum says 'I know I should have done that' and everything carries on as it is while nothing changes. God-forbid anyone gets annoys with the GP for not tidying up because mum goes nuts with you. Can't win.
Fat does not make you fat. It's actually pretty important.
