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.
