Light Spread of Butter on Your Bread

They say that the good die young. Great... but what exactly constitutes "young"? (I keep hearing about 40 being the new 30, or some such bullshit... tell that to my liver) And good? Not to get into a pointless discourse about semantics or anything, but just what the hell counts as "good" these days? For me, "good" is a grilled cheese sandwich... with the bread nice and crusty/toasty (but not burned) and the cheese (American slices, of course) all ooey-gooey! That shit is good, but, as far as I know, a sandwich can't die... it can be eaten, by me, with great, almost frightening voracity (and a nice, cold glass of milk), but it can't die. That being said, I've not run across too many old sandwiches in my time.
