As a kid a loaf of bread only lasted a day or two with 6 people in the house, so the heel was the best part.
Now that I'm an adult living on my own, the heels keep the rest of the bread "fresh" until it goes moldy and I throw the remainder away, including the heels.
I usually only get through 3/4 of a loaf at most, unless I have a stoned grilled-cheese night.
