Exactly! That new graph is way different. The old one showed a guy with a BMI of 20 being the same as a massively obese BMI of 40 as far as death rate goes.

The new one is much more like one would expect once all the skinny smokers are cleared out, 20 is about the same as 30 - and a BMI of 30 is much less outrageous than 40.

The first graph was pretty misleading, and I wouldn't say this is the same result - but I think I see what you're trying to argue and that is under weight and overweight both have increased risks. With that I agree.
