Jacob and his powers

"He inhaled deeply, and then let out a gutsy sigh.
  "Fine."
He unwound the towel and, when I reached out to take the cloth, he laid his hand in mine.
  It took me a few seconds. I even flipped his hand over, though I was sure he'd cut his palm. I turned his hand back up, finally realizing that the angry pink, puckered line was all that was left of his wound."



How cool would it be to accidently get hurt, just to see that would heal faster than you got it?? I think it would be great, because it would also be a life saver. Sure, bigger wounds would take longer to heal, but they'd heal. Too bad real life different, but also thank goodness.
