Briefly "forgetting" you're tired thanks to an adrenaline rush may work for a little bit, but not forever.
It's been commented on that a lot of technical stuff is being explained in this story, which is fair. It's something I feel is fitting and all that, and I've no intention of stopping if and when I think there should be some, but it's fair. I've started hanging a few lovely lampshades to spruce up the place, however.
Confession: I hear Super Mario sound effects when I see uses of "shrink" or "grow" as in recent comics. I have no idea how you'd write those out, and I know actual English words a person might say are nowhere near whatever they would be, but nonetheless.
