Space Shuttles For The Win!
So here's an interesting question that I've never asked myself before but suddenly realise I can't answer:
Why does motion sickness cause Nausea and vomiting? I don't mean "why is motion sickness". I get that it's about conflicting sensory input. What I wonder is, why does it cause this specific reaction?
Like, if I have a fever, my body starts sweating, which is reasonable as it helps with cooling. If I ate something bad, I get sick and throw up because the body needs to expell the poison, also very reasonable. But when I'm off-balance, the same happens? I can't see any practical use in the physical reaction. No evolutionary advantage. My best guess right now would be that maybe some common forms of poisoning can cause dizzyness, and that motion sickness effectively triggers an anti-poison response from the body...?
And now I also know where the fantasy caravan-sim "Vagrus" got its name from. Thanks a lot for the unexpected bonus!The name of the vagus nerve comes from a Latin root having to do with wandering
Taking blood samples from my autistic son: Difficult, requires a lot of patience and efficiency, but can be practiced under non-critical circumstances to get him used to it and get better at doing it.

I would be interested in knowing how you dealt with that experience afterwards. Did it make future events even more traumatic, and did it make you resent your parents, or could you file the whole thing under "needed to be done" and move on?and had to be overpowered for one surgery at age 13
