"US obesity rates jumped in the 1980s and 1990s, and the vast majority of the population affected by obesity had not yet reached age 65 by 2000," the Boston group stated.
"As the large baby boom cohort begins to turn 65 in coming years, a stronger connection between obesity rates and life expectancy may emerge."
In other words, as the nation's middle-aged fatties reach retirement age, more and more will start to die out. Life expectancy in the US could then actually go into decline.
