Riddle of the Day

[Gizmokid2005]

I can be found where anything cannot;
dead men eat me all the time,
but if a living man eats me, he'll die.


What am I?

ANSWER (Must've been too hard for TL): Nothing.

NEXT RIDDLE:

I have two arms, but fingers none.
I have two feet, but cannot run.
I carry well,
but I have found I carry best with my feet OFF the ground.


What am I?
