What's the difference?

[Jazzy]

What is the difference between living and existing?

 

[Nebulous's iconNebulous]

Just existing is when you have no joy in life what-so-ever I suppose

 

[Evil Eye]

Go outside and fetch a rock.
Does it exist? If yes, is it alive? If no, try again.
If it's alive, try again, it's probably a tortoise. If not, your question's been answered.
