Does worms can still be alive after you cut them in half?

They will not live. However, they will stay alive for a few hours just as a chicken will stay alive after chopping off it's head for a few minutes.
actually they will live. they will grow tails again. I have played with worms since i was a child. They have more than 1 heart and more than 1 brain.
a planaria worm will grow back in to two separate worms if you cut it in half, Yes this is the right answer but i think they have 4 hearts and live forever and they grow back
