Answer:
I have a neck and no head, two arms but no hands. I'm with you to school, I'm with you to work. What am I?
I can be thin but not fat; in your body but never on your placemat. I'm always better when I'm fresh but you'll never see me in the flesh.
I am a mountain at night meadow at day
I fly away as soon as you set me loose. People around you may slowly move away once they sense my presence.

What do you purposefully put lots of in and on your body, but run away from when you encounter it outside?
