I know what you mean. It's fascinating in that it's so unrelatable. It's like trying to imagine being two dimensional or having an exoskeleton. The reality is so foreign that I can't even begin to think of what it's like. How does a stomach end all the way down there? How can you never see your own feet? How can you struggle to stand up? What's it like to be able to grab buckets of loose flesh? I'm curious in the same way that I'm curious about anything I don't understand. They are so weird and what I can't ever seem to get over is that it happens solely from eating too much. Such a simple thing, eating, that we all do, and yet it has the power to disfigure someone to this degree. People suffer violent burns and lose limbs and are still more recognisable as human than these things.
