Left a Block of Cheddar Cheese on the KItchen Counter All Day

Ask any college kid who's left pizza on the counter and snacked on it all weekend.
I used to do that too, but at age 65, I'm starting to see the finish line, so tend to be a lil more um, conservative,lol. But it might be in the fridge a few days, or a week, before I get back to it. My wife hates me doing that tho, so sometimes she scarfs mychit down,lol.So far it's only hurting her waistline...............
