Why doesn’t spinning affect some dancers and circus people?
I think the answer to that is they actually use a special technique when they spinning round. If you watch a dancer who’s spinning round very fast they’ll flip their head round, very quickly so their head is actually fixing on one point and then flipping round very fast. Is this called spotting? This is what we think it’s called. Your head’s actually mostly stationary and you’re flipping round and focusing on one point so it affects your ear system a bit less.
