If I eat, I would live. If I breathe, I would also live. However, if I drink, I would die. What Am I?

No one can see me, hear me, feel me, or smell me. Yet, if you tell me... I can do all those things and more. Every person, animal, amphibian (or more) needs me. Without me my wielder will die.

I have a foot, yet no legs. I have a house yet no furniture. I choose to be on the move, but moving isn't so easy. What am I?

I can be cracked, made, told, and played. What am I?
