In a world without gravity, one would be weightless, but always nauseous. Because of this, it would be very difficult to complete a lot of your daily activities without throwing up. If you tried to eat something while you and your food are floating around, you will probably have a lot of trouble trying to hold your food down. In 0-g, life would be very hard. Roller coasters are a perfect example of this. I do not do well on roller coasters.
I get sick when I encounter zero gravity for that split second on rides with loop-dee-loops and the like. This is how I know I would really suck at surviving if there was no gravity. Not only would I be constantly puking, but I wouldn’t be able read or really even enjoy doing anything except floating around trying not to dry heave. So, I wonder how someone, mainly me because I do not have a strong stomach, would merely perform the act of drinking a glass of water and thinking at the same time in a world where everything floats.
Without the force of gravity acting on all objects, there is nothing keeping us attached to the earth. We would simply float away from the earth unless we nail out toes to our floorboards, and our entire house to the earth’s crust. So, drinking water…this would not go very well for me. Not only would the water not be forced to stay in its proper area of residency, the cup, but it would be poured on my face if ever I tried to drink it, and that is most certainly NOT WHERE IT BELONGS.
