Answer:
I am the only vegetable or fruit that is never sold frozen canned processed or in any other form but fresh.
People see through me, but none pass through without killing me. I can be anywhere, and can be seen double or single. What am I?
Find me on body builders or in the drink aisle.
Though not a plant I have leaves. though not a beast I have spine. Though many wouldn't need me I am more valuable than wine.
When you are inside me you will be encouraged to slam other cars.
Give it food and it will live, give it water and it will die.
