Question
How did Harry's grandparents die???
The Potters : Okay, maybe something to do with the dark lord or something like that. Wizards ain't the safest lot.
The Evans : HOW DID THEY DIE? OLD AGE? LIES!!!!
Evidence : Lily was 20 when she had Harry.
She was born in 1960. It's safe to assume that her parents were like in their 20s at that point of time ( uh it was the norm). So they'd be in their 40s around the time lily dies. And in their 50s when the books take place.
YOU DO NOT DIE OF OLD AGE IN YOUR FORTIES.
