First of all, I took on this challenge.
Could have been @IronSoldier16
You and him stuck in one room for three days?
My bet would always go with Manuel.
It’s not about choice of weapons but motivation.
I go with second. I don’t want to be blind, and I’m never alone with my dogs.
WYR chrash your car on a regular basis or ride for ever just bike?
Aye. We’ve established this. I’d break that man like a toothpick with both hands tied behind my back. No doubt about it. Would I want to? Nah, he seems like a good dude. But if he tried anything he’d have to catch these hands.
Lol. I wasn’t meaning you’d go blind. Just be alone forever.
Lol. The bike 
WYR never be able to cut/shave any hair on your body again or lose a finger?
Dang, I loose a finger. 
Wyr got nuts from time to time or be bored forever?
Imma take advantage of that typo real quick and say I’d like to have nuts from time to time.
WYR have all the floors in your house carpeted or just bare concrete?
All the floors in my house are already carpeted (apart from the bathroom and kitchen) and it’s shite. They’re dirty, they absorb dust, bacteria and smells and (in the case of ours) get eaten by moths. Bring on the concrete.
WYR swap bodies with me or @jrtrussell?
Ok @jrtrussell you wanted this. I go with Jareds body. One reason, I would like to be in the US again. The other ones, I won’t say, I’m not mean 
Wyr urg, think, think 
have an choleric or phlegmatic temperament?
You’re trying to see the list in real life?
Lol. I had to do a little bit of googling for this. I’d take phlegmatic.
WYR have to use a flip phone or a bulky desktop computer from the 90s?
Flip phone
(And now a follow up to the body switching one)
Wyr be stuck as @jrtrussell @IronSoldier16 @gatsie or @intheend for a whole week?
@intheend so that I can delete her account on here or get her IP banned, then I would have vanquished my nemesis.
WYR play sting pong or have a paper hornet fight?
Hornet 
Wyr be buried under snow till death, be set on fire, or be buried alive?
Needed me quite some time to get what you even ment by this. so, no. 
I see, no contact at all to any waldorf school stuff. Luck you I have a choleric temperament. You sure noticed already 
I think, I take the snow. It’s hopfully the fastest and less painful as the others.
Would you rather be free of physical or mentally pain for the rest of your life?
you know i figure this could be hard for some people, but im such a food lover, id much rather have no sense of smell plus there’s so many bad smelling things in this world, you have the choice of whether or not you want to eat something, but you can’t always avoid a bad smell
WYR have brain surgery with no anesthesia so you could hear, smell and feel everything
or do the exact same thing to someone else yourself
Totally with you. If I have one missing sense, then smell. But as a person who actually can’t smell, I would love to get it, know how it is.
Someone else
Still this:
Physical.
WYR Drink your own pee or eat your 
for one million dollars?
Oh my gosh you are hilarious.
Uhhhh, neither
WYR jump 3 weeks into the future or 3 weeks into the past?
3 weeks into the future, then I would have finished my next work block.
Wyr eat the rest of your life sweet stuff or never again?
lol. Never again.
WYR see everything in black and white or hear everything an octave higher than it actually sounds?
See everything black and white. Like most folks do
WYR be self-employed or employed?
Depends on the scale of the business and what it is I’d be doing.
WYR spend the rest of your life speaking like a hillbilly or a chav?
