Exactly. The only reason the numbers of years reduced in lifespan is so low is because of modern medicine and the billions of dollars spent on health care for obese patients. The fact is, science can keep almost anyone alive indefinitely, it just depends what one's definition of life is. If the obese did not have acess to diabetes medication, heart pressure pills, heart valve transplants, gastric-bypass surgery, chemotherapy for the various cancers they're more likely to develop, and the aid of 24/7 caretakers, they'd be dead llooooonnnggg before their "merely 3-years" shortened lifespan.
