...Harbison, who can list a Pulitzer Prize and a MacArthur Foundation “Genius” Award among his accomplishments, settling on a career was never that difficult. He started improvising on the piano at the young age of 4 or 5; at 16 he won the prestigious BMI Student Composer Award. Now, at the age of 71, he is considered one of the most prominent musical figures of his time...
...researchers tracked a group of over 19,000 women aged 38 to 89 and periodically assessed their body mass index, eating habits, and other health indicators. The women were all healthcare professionals who started the study in good health and with a BMI within the normal range...
...Framingham score is a decades-old tool established by a landmark study that began in 1948 (and continues today), which identified seven major predictors of heart disease - older age, diabetes, smoking, high blood pressure, high total cholesterol, low HDL cholesterol and a BMI in the overweight or obese range. The Reynolds score is a more recent screen that uses the Framingham risk factors as a base and adds another, inflammation, which in recent studies has been linked to an increased risk of heart disease.

...study has a few limitations, however. First, it used height and weight measurements that were reported by participants - which can be imperfect. (People tend to overestimate height and underestimate weight, which skews their BMI.) It also collected height and weight information only once, at the start of the study; researchers could not have known, for instance, whether people might have unintentionally lost weight before the study or during the follow-up as a result of underlying disease. Furthermore, the study's participants had a lower overall mortality rate than the general population, suggesting they were healthier to start with. Many...
Where researchers may agree is that BMI is an unreliable marker for body fat, or health, in the elderly. As people age, they lose muscle mass and bone density, which leads to weight loss and a declining BMI, despite an increase in body fat. Manson suggests measuring waist circumference instead, which is a more accurate gauge of abdominal obesity and tends to predict a higher risk of death in all age groups...
