Let me rephrase what I said:
There are an infinite number of alternate universes/timelines.
There is undoubtedly several million universe instances in which you're black. The same goes for every non-black person on Earth.

Man, alternate timelines are so weird.

I'd make it so we are not bound to the shape of our body's and can change shapes. Or in the least just me.

So you wanna be a squid?

That's not physics, that's biological manipulation.

This topic should be "So you have the ability to change any aspect of existence..."
That would result in a lot more fun responses.
