Answer:
I am the only thing that place today before yesterday. (one word)
No legs have I to dance, no lungs have I to breathe. No life have I to live or die, and yet I do all three. What am I?
I begin and have no end. Eventually I will be the end of all that has begun.
When you stop and look you can always see me. If you try to touch you cannot feel me. I cannot move but as you near me I will move away from you.
I have a hundred legs but cannot stand a long neck but no head and I eat the maid's life. What am I?
Give it food and it will live, give it water and it will die.
