How do wreastlers come out ingured from one match and come back looking unharmed?

1. Wrestling is all staged. it's fake. I know, you're shocked.

2. The matches are all recorded; two matches may be recorded months apart, but broadcast one after another.

3. For all that wrestling is staged and fake, the wrestlers ARE professional athletes and are in tremendous physical condition. They heal quickly. And since they are actors, if they actually are injured, they can re-write the script for the next bout to minimize and de-emphasize their injuries.
