Humanity is often said to have 5 senses, but this isn't entirely accurate. This is one question of several in a series I am asking regarding going beyond the 5 senses.
One of the senses is something I am just going to call "body sense" as a catch-all for these:
Equilibrioception: The sense that allows you to keep your balance and sense body movement in terms of acceleration and directional changes. This sense also allows for perceiving gravity. The sensory system for this is found in your inner ears and is called the vestibular labyrinthine system. Anyone who’s ever had this sense go out on them on occasion knows how important this is. When it’s not working or malfunctioning, you literally can’t tell up from down and moving from one location to another without aid is nearly impossible.
Proprioception: This sense gives you the ability to tell where your body parts are, relative to other body parts. This sense is one of the things police officers test when they pull over someone who they think is driving drunk. The “close your eyes and touch your nose” test is testing this sense. This sense is used all the time in little ways, such as when you scratch an itch on your foot, but never once look at your foot to see where your hand is relative to your foot.
My question is this: How might a race whose body sense is ratched up to extreme levels (say 4 times the normal human level) perceive and interact with the world?
