I was told of a friend of a friend who lived on noodles and water for 1 month straight. And then he died. Not sure of the cause of death. Not sure if it was ramen either.
There's nasty, potentially lethal bacteria growing if you keep noodles or rice for days in warm environment. Best to put in the fridge after cooling down (post cooked).
I saw a report a few months ago where an asian dude died because of a bowl of rice he kept in a pot with a lid for 8 days before eating it up.
