But Mark is built like a tank because it's more like someone took Ivan and compressed him down to Miles's height (or, well, didn't let him grow taller), so he's got the musculature and metabolism of someone over a foot taller. Mark is even less "natural" body-type-wise than Miles. Aral's kind of square, but Cordelia's lanky, so it's unclear what 6-foot-tall Miles would have been like.
