Subject: Short term evolution of human race

Given that there is an increasing tendency towards overweight and obesity,

as defined by Body Mass Indices >25, is there a trend towards overweight

becoming the norm, and hence the need to redefine "normal" weights for height,

and is there any evidence that being overweight as opposed to obese (i.e.

having a BMI between 25 and 30) does lead to increased morbidity?
