Life expectancy to drop

I've been looking into this issue that I posted in December last year. The original article from the New England Journal of Medicine: March 17, 2005, vol 352, 1138–1145; 1135–1137 would be worth a read, but if you don't have access try a media report like this one: Life Expectancy to Drop for first time in 1000 years. It is mostly obesity and ill health associated with obesity which is to blame for the reduced life expectancy for future generations.
