Opinions vary. When I was in College the local Burger King would have $0.50 Whopper night, and I'd buy a few bucks' worth, keep 'em in the fridge, and eat 'em cold as a snack.
Ewww........
One of the joys of aging, is to escape the tyranny of the young male appetite.
It is wonderful to enjoy 2 whoppers and a coke as a generous meal rather than as a mere snack.
Ever eat cold pizza right out of the fridge, without heating it up?
