As soon as I saw the headline, I thought to myself "well yeah, Americans have also never been fatter," so the conclusion wasn't much of a surprise. Interesting that it's affecting men so much more.
This isn't the only study that indicates fatness is impacting aggregate performance, either. The US DoD has actually identified American obesity as a potential threat to national security and readiness. [1][2]
If you wish to phrase things that way then feel free to reinterpret the discussion chain thusly:
1) spyhi used a continuous scale: "also never been fatter"
2) _qhtn switched to a discrete scale: "Do fat Americans run"
3) I replied to that question, that yes, "fat Americans run", objected to _qhtn's discretization of a continuous scale, and gave a pointer to a paper regarding BMI, which assigns categories like "overweight" and "obese" to the continuous scale.
Your comment comes across like you think I didn't know the difference between continuous and discrete, when that was the point of my response.
