Daredevil (film)/WMG

Daredevil has a healing factor
It's almost certainly just a case of lax storytelling, but I have heard this hypothesis put forward by two completely independent sources (my dad and another friend of mine), so here it goes: In the movie version, Daredevil not only has superhuman senses and agility, but the power to recover from injuries extremely quickly. It's the only way to explain his wildly fluctuating physical condition over the course of the three successive big fights he gets into. (Maybe that radioactive gunk had some of Wolverine's skin in it?)
 * Unlikely, he's covered in scars and shown taking pain medication. He also had to pop his knee back into place at one point.
