Answer:
I can be hairy and itchy all over. I hang on a stick. I can be the scariest thing you have ever seen. I stand in the middle of nowhere.
I can bring tears to your eyes; resurrect the dead, make you smile, and reverse time. I form in an instant, but I last a life time. What am I?
I regularly change shape yet remain a sphere. I am always there but not often seen. What am I?
Always in you, sometimes on you. If I surround you, I can kill you. What am I?
I ask no questions but receive a lot of answers. What am I?
The warmer I am the fresher I am.
