Answer:
What can you lose that will cause other people to lose theirs too?
I can sizzle like bacon. I am made from an egg. I have plenty of backbone but lack a good leg. I peel layers like onions but still remain whole. I can be long like a flagpole yet fit in a hole.
I am a box which holds keys but not locks. With the right combination, I may unlock your soul. What am I?
Who makes it, has no need of it. Who buys it, has no use for it. Who uses it, can't see it. What is it?
I am a desire to munch
What is always coming but never arrives?
