If there are some humans with 4 types of cones in their eyes (tetrachromats), is it possible there are humans who have the fourth type of cone but not one of the other three? Would these people even be aware that their vision was special in any way?

How much of the human body is actually water? I've seen anecdotes claiming everything from 60% to 95%. Also is it even accurate to say things like blood, cytoplasm, and cerebrospinal fluid are water-based, or are they a mixture of chemicals all their own?
