Ah, ok. Sorry for not making that clear. So here's what I think:


 * In the manga and anime, Luffy can selectively choose which parts of his body to use Gear Second on, and isolate it there.


 * This task would be impossible to do in real life, for the reasons I listed earlier.


 * The anime's portrayal of the selective Gear Second usage are "legit", meaning that they are canon.


 * The blood-pumping action showed in the anime following the timeskip may not be accurate, as it has yet to be shown in the manga.
