Motion of seasickness put into perspective

Have you ever wondered why passengers seem to get sea sick more than the Officers navigating on the bridge of the ship? Or why passengers in the back seat of a car are more prone to chunder? I took me a while to realise this but I have finally found out that most people like to have a sense of direction of knowing where they are going. From the bridge we can see what is actually going on and predict the movement of the vessel from observing the approaching sea conditions. So for a passenger who is indoors all they know is that the vessel I rolling around and their head then starts to signal to them that something isn't right. I bought a passenger up to the bridge one day who suffers from real bad sea sickness. She said that she has never been on board a boat or ship before and not been sick. This lady did the whole voyage across from one port to the other on the bridge and didn't feel the slightest urge of sea sickness. Being on the bridge of the ship she could see where we were going and what we expecting to encounter, wind gusts, sea waves and long swell waves. We sometimes get like this in life as well. If we can't see where we are heading or have no sense of direction we start to feel a bit sick. It's just a matter of opening up your eyes and looking forward to what is in front of you instead of down at the inside of a white paper bag.
