I know, I know, you're a three-dimensional person. (Or are you? On the Internet, nobody knows you're a pancake. Or Kansas.) But we're told that doesn't matter:
Up until the late 1990s, it was commonly thought that 3rd Dimensia was only a disorder for patients dealing with 2-to-3-dimensional crossover. But today, scientists and doctors know better. Be warned: 3rd Dimensia does not discriminate. It can strike anyone at anytime.One of the diagnostic questions is "Do you settle for just jumping over objects and projectiles?" -- I suspect that part of the reason video game characters can jump so high is because in two dimensions there is only one horizontal dimension, so the more realistic option of swerving around an oncoming enemy simply isn't available to them. If this is so, then I'd suspect characters in 3-D games can't jump as high (relative to their body height) as those in 2-D games; at some point the designers should have realized that real people don't jump that high, and designers probably feel more constrained by real physics in 3-D games than in 2-D games.
Try as I might, though, I couldn't find a reference on that site to my favorite fact about two-dimensional life -- namely that their digestion must work differently from ours, because topologically they are unable to have a digestive tract. Presumably they'd absorb nutrients through the skin, like unicellular life forms in our world do. I suspect larger 2-D life forms would have fractal surfaces, to get a large surface-area-to-volume ratio, similarly to how we have branching networks of blood vessels so that oxygen can get to all our tissues. This is one thing that Edwin Abbott Abbott got wrong.
