My head hurts now

There is a book written in brail that describes colours for blind people. Water does not have a taste, you are tasting your own saliva and any impurities in the water.

I would say left is the side your heart is on, and right is the other(unless your heart is on the right, in which case it's the opposite)

Red is the color of authority, of power, and of anger. Thus the term "seeing red".
