Imagine if you find out that normal humans could breathe underwater, and there 100 billion people living underwater. Us 8 billion people unable to live underwater are the "iron lung kids".

The all say "imagine not being able to 'fly' underwater, or not riding a gigantic squid - I would kill myself to end my misery!"

What would you respond to that? I'd be like "eh, must be nice, but I've lived above water all my life. It makes no difference to me."
