How would you make time pass in an empty room?

[Ekit]

So the swedish journalist Dawit Isaak have been in prison in Eritrea for 9 years without trial.
My question is: If you were in stuck in a stone room without company, furniture and windows for 9 years, what would you do to make time pass?

 

[Marter]

I would be engulfed in deep thought. I can have good conversations with myself at times, and that is what I would have to do to pass the time.

9 full years of masturbation.

What else?

 

[El Poncho]

I would sing and dance like a musical.

9 full years of masturbation.

What else?

This, obviously.

 

[TunaKing]

Sing songs, no matter how bad i sound. I'd rock out too and dance. Although 9 years... i imagine you might forget how some songs go, that would be horrible.

 

[TheBluesader]

Write a huge fantasy epic in my head so I could put it down on paper when I got out.

And everyone would buy it, even it was terrible, because of how and why I came up with it.

 

[Trivun]

I have a very active imagination, so I'd use the time to come up with alternate worlds and fictional characters and stories, and live in a world of my own imagination. It'd be something to keep my mind occupied while I live out those nine years in a prison cell, and something great to write about when I'm finally released (I'm quite interested in writing fiction, you see, both stories and screenplays...).

This is the only answer.

 

[rokkolpo]

masturbate. (damn ninja'd)

no i would kill myself after 2 years.(at best)
9 years is a lifetime. no way i'll stay there for 9 years.

on to oblivion!

 

[The Night Shade]

Draw with my teeth a work of art

 

[mexicola]

First I would go insane, then I would have a hell of a time.

 

[lacktheknack]

Whatever I did, time would still pass. So does it matter?

Oh fine, I'll bite.

I'd chew my way out.

 

[Quaxar]

Learn to play the air guitar, then pretend to rock all Guitar Hero songs on expert. As soon as the guards get curious tell them about the "wonderful possibilities of fantasy", kick in their heads, put on the uniform and walk out. Easy as that.
Infact, I've done it several times no-... err, I mean I was told about it!

EDIT: or Oldboy-style

 

[Optimus Hagrid]

I would sleep a lot, learn to meditate, try and lucid dream, wank, make friends out of patterns on the stone walls, chew my fingernails, try and create as large a pile of bodily excess as I can (not stuff that usually goes in the toilet, of course), create musicals and break down mentally. Sounds like fun!

9 full years of masturbation.

What else?

I'm thinking this...simultaneously...I will also try to convince the guard to give me chalk or a marker to write on the walls in between chats with myself and a sore left arm

 

[RMcD94]

Whatever I did, time would still pass. So does it matter?

Exactly what I was going to say.

I'd probably repeatedly knock myself out because it'd be boring.

Or, write a book. Call it My Book and sell it to the masses and then becom-

Oh wait, someone did that.

 

[The Harkinator]

I was gonna say walk out, then it turned out it was 9 years in prison. Erm, get a computer and start posting comments on internet forums
