Good news for those who are considered "overweight"... your incidence of death and disease is actually lower than those who are "healthy" or "optimal":

Overweight was associated with significantly decreased mortality from non-cancer, non-CVD [cardiovascular disease] causes but not associated with cancer or CVD mortality.

It's unclear what this means for me.  Whenever a food stuff is considered bad for me, it's been suggested to be banned.  Now that it appears that my BMI of 21.8 is "sub-optimal" by this new study, it's unclear whether those same people will insist I eat more and become fatter.  Will I be tied down and force fed?  Will they steal my bike from me?  Oh wait... they can't do that... then how will I lower my carbon footprint?  Too many decisions for other people to try to make for me.
