Yummy too, and a lifesaver!
If you're ever stuck in the woods and can't find your way out, you can lick your own optics clean. We've heard of astronomy expeditions surviving a week on the beads from three secondary mirrors along with the bubble gum holding the primary.
And that's not all - cheese whiz comes in many different flavors, including fiesta jalopeno chiles, so if a grizzly bear demands a lick, he'll be very surprised. Better than pepper spray and, as Jim says, much much cheaper.
But stick with low-fat - those tras-fats will kill you. -l
