A spirited jig I dance bright, banishing all but darkest night. Air can't kill me but water can. Share me, I won't get less unless wind ruins me. What am I?
You do not want me when you donβt have me but when you have me you don't want to lose me.
What gets sharper the more you use it?
I am not alive but I can die. What am I?
What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
