Frayed Cords

We are an Apple family.  That means lots of computer and phone cords.  While the actual devices are wonderful, the cords...not so much.  There seems to be premature fraying on most of the phone cords.  They need to be replaced for safety sake.  The old, frayed ones need to be THROWN AWAY, not kept to be taped or something.  Once something is replaced, get rid of the old one, especially if it isn't in good condition.
