Picture this...

[Composer]

I'll take the book, walk up to a random person, hand it to them and say, "Written in this book is how you will die." Then I will walk away.

GENIUS!!!

 

[MasterChowmein]

I read the book, then give it to the police and see if they can help me.

 

[Just_A_Glitch]

Read it.

I'm not really afraid of dying, so it wouldn't really change anything.

 

[Julianking93]

Nothing good can come from such a thing.

I'll spend the rest of my days fearing whatever it is that takes my life away.

I'd burn it.

 

[TriggerUnhappy]

See how I die. If I know how I die, I can do potentially deadly things, knowing that they won't be how my life ends. Then preform rituals to prevent myself from dying in the way the book says I will.

Exactly, I'd read the book, then essentially live the movie Big Fish.

 

[ottenni]

Sell it and blow the money on cocaine and hookers. Its called dying with style.

 

[Daniel Cygnus]

Take a look. I figure if this person is giving me this information, there's got to be a reason for it.

 

[Citrus]

I'd apparently be one of the the only people who'd immediately assume it's a prank/joke and not take it seriously or care what's inside.

 

[Spiner909]

I publish the book and make massive profits off it.

My life is awesome, therefore my death will be awesome

Brilliant! This.

 

[Kamaitachi]

I publish the book and make massive profits off it.

My life is awesome, therefore my death will be awesome

This.

 

[Yumi_and_Erea]

Throw it on the pile, I s'pose.

 

[kilibot57]

Make a movie about it

 

[Aesir23]

Read it, if I know HOW I'm going to die then it will lend some certainty to my future and I will feel more prepared when the hour of my death arrives.

 

[Frank_Sinatra_]

I'd eat it, then I'd become Death itself.
BWAHAHAHAHAHAHAHA!

 

[Agoreophobe]

BIG fish

 

[the1ultimate]

Well, I would read it.

Knowing is always better than not knowing, right?

Also, there is always the possibility that I could change it, unless it says "Dies peacefully in sleep, aged 112 surrounded by family and friends."

I might also consider burning the book, since it's no worse than I've done to other books whose endings I despised.

 

[Beartrucci]

What do you do with the book?

Sell it. Some sucker into fortune-telling and stuff will probably pay good money for it.

More than likely this, because this idea is made of win.

 

[Simalacrum]

you know, looking at all these answers, its quite strange to see that everyone automatically presumes that the book tells truth, just becaus they're mind tells them so...

 

[ArcWinter]

Argh! You've changed the conditions!

For this new and uncertain model, I'd probably start eating the book. Mmmm, knowledge.

 

[primitivescrewhead]

Throw it away
