  > Coiling the cord by hand causes the wire to twist, which in turn causes fraying. Not if you know how to coil it properly - yet the sheath on the cable of my MBP PSU has split, despite not using the fold-up cable storage arms that would encourage bending the cable at an awkward angle.

  Sometimes I think that the usual workplace safety orientation videos should be replaced (augmented?) with videos like these, showing simple tips for how to keep the workplace from becoming a disaster: how to coil cables, how to do your dishes, how to walk down the hall without making everyone's desks vibrate, etc.
