Religion would no longer exist and everyone would think logically so we can finally achieve a greater peace in this country (maybe sorry if I offended anyone).

WWYD if you became allergic to your favorite food?

I don't have a strong preference and have a few favorite foods but can't name them off the top of my head, so I'd probably just avoid it without that many issues. If it's a very mild allergy maybe indulge myself every now and then.
WWYD if you could walk on water but only swim on land?

I would obtain all knowledge in the universe.

WWYD if you woke up to find yourself on the other side of the world?

Edit: I was answering sneepity's question, I didn't see SB's post. I would get a wheelchair when I'm on land so I could just sit and not have to swim.

I would embrace living the Aussie life and then take a tour of New Zealand.

WWYD if you got sucked into a book and became the protagonist of your favorite book/book series?

Oh my, time to find my dad who ditched me and make friends!!! (and almost die) (it might seem like a cliche story but it's really nOT)
WWYD if you suddenly coudn't speak?

Time for my basic ASL to kick in.

WWYD if you suddenly went blind?

I'm already almost blind without my glasses so I'd probably manage decently. I'd just be bummed that I wouldn't be able to see a certain someone.

WWYD if you were in the middle of playing a football game and three big, menacing dudes came running at you to tackle you?

Aww.
Uh, if I was holding the football probably throw it at them or someone else (I am not risking a concussion over a game). If I weren't and they were just tackling me randomly probably run to the side, or, if they were spaced out, see if it were possible to slip out through a gap.
Better question is why am I in the middle of a football game?

WWYD if you could no longer manipulate solids? (basically everything is suddenly too heavy for you to move but everyone else is normal) Liquids and gases aren't affected, so you can still breathe and in some cases drink water.

I would be bummed out. That means I can't do anything. not even write.... :c
I would probably live in a wheelchair or sleep. I would try to learn.
WWYD if you suddenly had to turn all your organs into machines, or you can't live?

I'd turn them into machines so I can live. I'd also make sure to keep replacements around and learn how to install each one in case of emergency.
WWYD if you had an identical twin?
