Sen. Marco Rubio is pressing his congressional colleagues to approve nearly $2 billion to fight the Zika virus.

A body mass index under 25 is deemed normal and healthy, and a higher BMI that's "overweight" or "obese" is not. But that might be changing, at least when it comes to risk of death. The body mass index, or BMI, associated with the lowest risk of death has increased since the 1970s, a study finds, from 23.7, in the "normal" weight category, to 27, which is deemed "overweight." That means a person who is 5-foot-8 could weigh 180 pounds and be in that epidemiological sweet spot, according to the NIH's online BMI calculator. The results were published Tuesday in JAMA, the journal of the American Medical Association. (Shute, 5/10)
