Okay. So you're in a white room. A room that never ever ended. With NOTHING in it but you, and the clothes you wear. No ipod, no watch, no nothing except your clothes/shoes. Oh, and you can't die. Hunger is of no issue. What would you do?
I'd train myself as well, seeing as that the room is the perfect opportunity to train.
So if you can't die, you cannot die of old age, but I'm sure in a few decades you'll not be able to walk for the rest of eternity, unless you do not age either, which would probably mean time means nothing in there.
I would probarly go insane. Or keep on running till i cant anymore.
It would be like that.
1. Walk for some Time till i rly cant
2. Scream and Swear cause i dont know wtf is going on
3. keep on running
4. Hurt my self
6. start thinking of stuff and start to create fake persons where are with me
7a. follow the plan of the fake persons where they say i should kill myself
7b. start laying on the floor and turning around and screaming and crying and go insane.
I would see ya all in the white room and start talking to you how to get out ^-^
Eh...I was kidding about the training thing. You know...cause I'd be the best martial artist in there since I'm the only person in there. Yep.
I'd probably catch up on some sleep. For the next 992923918238172931237812937128937289173891278931278931728931271829731927312897389217318927312893712937129837128937128973218973189273189273 years. I'm the God Emperor after all. After that time has expired, I'll get tired of sleeping and just walk out of the room.
