  1. The ring could tell you how much light your ring is getting, but how would it know how you're dressed. The amount of vitamin D you get would depend on how much of you skin is exposed and if you are wearing sunscreen. If I am in the sun wearing long sleeves,long pants, hat, sunglasses , and sunscreen on my face I am not getting the same vitamin D as being in a bikini and no sunscreen.

  2. I hate having to mute the annoying sound or music just to have to bring it back up when someone starts talking wish YouTube would make an easy way to tap the screen and you didn't tap it to hear what's going on
