How many times does Lee Da Hee get clonked on the head?

Just wondering if anyone is keeping track.  I'm pretty sure she gets bopped at least once each episode but sometimes more than once. 

Plus a Delayed Concussion huhu
This was according to the Doctor back in EP 7
I think one more hit and she dies TT-TT
-Unless her Father experimented on her ~ >.<
It was mentioned in one EP that her Father was a scientist
researching about making "humans who never get sick"....
This is just my speculation though BUT I really hope its true
since I want a happy ending for everyone and for
them to not die huhuTT-TT
