Lunching On Spagehtti That's Been in the Fridge Since 10/26/18

My wife made spaghetti a couple of days ago and she let me sprinkle 5 month out of date, moldy grated cheese on it before she informed me the cheese was moldy. Yikes! I scraped it off and ate it anyway. No food poisoning and it still tasted great. We threw out all the old cheese!
sister brought over a bag of cheese with black mold speckles in it, she thought it was Mexican cheese blend! I took a swig of a beer that was in a fridge for 7 years...wasnt my fridge, and the beer was found in the garage a week before I arrived. It was a little skunky. We found a C-ration of peaches out in the field and opened it, it still looked like peaches! Dated 1966....
