Artificial Eyebrows

  Did it ever happen to you that, on a hot day and/or your were working out hard, your sweat would run into your eyes and sting? Supposedly, the eyebrows are there to prevent that, but not always are they doing a very good job.
  Maybe it would be time to come with a man-made sweat-stopper, artificial eyebrows so to say. That may be something to stick onto your real eyebrows, or perhaps a device intergrated into sunglasses.
