Coma for 4 years

I find it quite amusing how people say, she came out of a coma practically normal, how can that happen? But they don’t mention how you can survive a shot to the head, or how a guy can fly, or how a single person can wipe out 50+ people or how swords are allowed on a plane or how there are no cops looking for The Bride the whole time she is in the truck, or how… I think you get the point now
