Hello! My name is Inigo Montoya. You are my age. This makes no sense.

I love catching mistakes and plot holes in movies and tv shows and I just found one in one of the greatest movies ever, The Princess Bride.  Inigo Montoya has been searching almost his whole life for the 6-fingered man who killed his father.  He is Very vocal about it.  He explained that he was 11 years old when the 6-fingered man killed his father and left scars on his face.  And he dedicated his life to finding this guy and avenging his father's death.  He finally meets him and eventually kills him - which by the way that scene also makes no sense b/c the 6-fingered man stabs Inigo Montoya in both shoulders and his stomach, and it seems like Inigo is going to die, but he somehow finds the strength to get up and kill the 6-fingered man - WITH THE SAME STABS!  Inigo stabs the 6-fingered man in both shoulders and his stomach.  Same thing.  Yet the 6-fingered man dies and Inigo goes on to live a nice long life.  It makes no sense.  But ok, back to my original point.  When Inigo finally meets the 6-fingered man, whom we met already earlier in the movie, doesn't it seem like the 6-fingered man is a little bit close in age to Inigo?  Like they could both be in their 30's.  So how old was the 6-fingered man when he killed Mr. Montoya senior?!  Because if Inigo was 11 when that happened, and the 6-fingered man is around the same age, was he like 14?!  Then how could he have killed anyone?!  It makes no sense.  I want to tell IMDB.
