What is it?

It's a sickness, a drug, a medicine, a thought, a bond, a theory, a form of insanity, a personality trait, a romance, an anti-septic, a handicap, a nuisance, a tool, a facade, a pain, a disorder, a feeling, an expression, a myth, a religion, a way of life, a goal, a challenge, a fever, an advantage, a life, a death and everything.

It's, *GASP*, love.
