It's complete bull shit. Fats will require more hospital visits and more care and treatment in it's shortened life than a healthy thin person. The NHS for the UK is already being strained by obesity and they have resorted to denying fats non essential surgery and care to help save some money. The part about saving money on pensions is probably true but unless it's a government employed the tax payer doesn't see any savings. Also you could argue that since fats die earlier they end up paying less taxes than us which puts the burden on us again. Once again fats have proven themselves to be a burden to all parts of public and private society with the only potential positive of saving money on pensions. However the negatives outweigh that one positive. Heavily. Yes puns are intended.
