On the subject of looking around at G's, I was at space camp a while back, riding the centrifuge to 4 G's, when all of a sudden I thought I heard a voice talking to me, looked around, and ended up having to stop. I dashed out of the door, ralphed my roast beef sandwich and fries into the nearest trashcan, and fell asleep on the ground for about fifteen minutes (as said by the other kids). So if we can't have G force feelings of sluggishness, we should at least feel some resistances of the looking around.
