A goodly chunk of electrical tape, thicker near the charger and tapering off farther away, can provide some bend protection and strain relief. Also, when you wrap the cord around the charger, use your index finger to prevent the first bend. You need to tape protect near the MagSafe adaptor as well. And stow it in your bag with the first bend facing out of the bag (less strain) rather than in the bag (more strain). I'm on three years with a MagSafe. It looks like hell but it still works.
