They drive you insane until you're so annoyed that you forget to eat or drink. So you die. (I just breathed while trying to eat a piece of ice iM CHOKING HALP)
By wanting the ring so bad, you turn into a shriveled, hunched over, aged, hairless, and grumpy creature (well this). You say "My precious..." until you die because your vocal cords erupt into little micro bits.
You spoiled the ending of the story, so your head is banged repeatedly with the book until your brain explodes of knowledge and gets squashed. Sweetheart, never spoil endings. EVER.
