[sub]Sigurd perceives everything, including himself, in slow-motion.

To better describe what I mean by 'fast-reaction, normal body', let's say there's a button. The objective is to press it as soon as it lights up. Sigurd will react immediately, before any normal human, but the time from when they start moving to when they hit the button will be the about the same.

I guess that rather than saying "he reacts instantly", it'd be clearer to say that "he has much more time to notice something". If something came at him from outside of his vision, he'd first have to recognize, "that's a bad, time to get the heck outta here" before he can move.

The time he has to notice it is extraordinary long, allowing him to start moving(react) "virtually instantly". In the case of the bullet, he won't be able to hear it coming since it's traveling faster than the speed of sound.

I hope this cleared things up[/sub]
